What Laws Must a Christian Follow?

The tension between the Law and the Gospel and how they relate to each other is the key to understanding Christianity.


The themes of law and grace are central to Christianity. Sorting them out gets to the very heart of the gospel message. Yet, many people inside and outside of the Christian community are unclear on what laws Christians must follow, what laws are no longer applicable, and why.

Perhaps, more importantly: is that even a question we should be asking? Someone recently posted the following question to a group to which I belong on social media:


I get the message of we are not under the law but under grace. But if we live through Christ we will follow the law. How do we know what law to follow? Does this go as far back as to not mix fabrics? 

Obviously everyone says we’re no longer under the law, but ”faith without works is dead” so I am confused. 

How do we know which laws to follow?


Human tendency is to want a list of rules to follow so we can check them off. The rich young ruler demonstrates that human tendency when he came to Jesus one day and asked, “Teacher, what good thing must I do to get eternal life?” (Matt. 19:16)

We also have a tendency to want to quantify rules, and to simplify them to make them easier to follow. Perhaps, that that is what motivated the Pharisees one day to ask Jesus, “Teacher, which is the greatest commandment in the Law?” (Matt. 22:36)

Or we go the other direction: we add rules on top of rules on top of rules to make sure that we don’t miss anything. The Pharisees demonstrated this approach in how they handled the commandment to observe the Sabbath. The created a list of “work” that was forbidden including, among other things: sowing, plowing, reaping, binding sheaves, threshing, winnowing, selecting, grinding, sifting, kneading, and baking bread; twelve similar activities related to the preparation of clothing, from shearing sheep to sewing; and seven activities related to preparing the carcass of a deer for food or leather. (See What are some Sabbath Observance rules that the Pharisees made?)

Moses started with ten commandments. By the time the books attributed to Moses were completed, there were 613 commandments!

The Torah (the Five Books of Moses – Genesis, Exodus, Leviticus, Numbers & Deuteronomy) focused on laws. That focus carries through the entire Old Testament. Though the observance of those laws can be seen more in the breach, than in the observance thereof!

The same focus continued into the New Testament. We see it in the question asked by the rich young ruler and the Pharisees’ questions to Jesus. We see it in the tension that threatened to divide the early church between Paul and Peter over whether believing Jews must follow the Law and what laws believing Gentiles must follow.

This is the tension between the Law and the Gospel. If we understand only one thing about the Gospel message, the relationship of the Law to the Gospel might be the most important thing! I have written about it often, including How the Moorings of the Gospel Were Secured.

For the sake of brevity, I won’t restate everything here. You can click in the links in the last two paragraphs to get an overview from the articles linked there. Understanding what Jesus meant when he said he didn’t come to abolish the law, but to fulfill it, is key.

If you are not a Christian, or you are a Christian, but you are not sure you understand these things, please do not just gloss over them. The tension between the Law and the Gospel and how they relate to each other is the key to everything.

It was the focus of almost all of Paul’s writings. It is the major theme in Romans. Take some time now to wrestle with it. Don’t stop until it makes sense to you!

Hopefully, the rest of my thoughts in this piece will help.

How the “God of the Old Testament” vs. God of the New Testament Idea Might Inform Our Politics

We should have the same mindset as Jesus in doing politics.


In the short YouTube segment, Are There Two Different Gods in the Old and New Testaments? (Part Two), Gareth Black does a good job describing why God appears differently in the Old Testament than in the New Testament. There is one God, but He relates differently to people.

I have explored this dichotomy before, but I don’t want to focus on it here, other than to set the stage for what I really want to lay out. The difference in the way God related to people at different times might just become a guide for Christians doing politics.

First, we know the orthodox view: that the God of the Old Testament is the same God revealed in the New Testament through Jesus. While, heretics abound, this is the accepted view. Still, it sometimes seems like a tough pill to swallow.

God in the Old Testament focuses on commandments. He seems full of judgment and anger. The Ten Commandments God gave Moses became legion with all the ceremonial laws, food laws, cleansing laws, and dozens of other laws people were commanded to follow.

In the New Testament, it may seem like Jesus paid “lip service” to the laws (saying he didn’t come to abolish the Law), because he simplified them into just two commandments: love God and love your neighbor. Easy, right?

At the same time, Jesus seemed to turn up the heat. In the same discourse in which he said he didn’t come to abolish the law, he told his audience the following:

  • It’s not enough to refrain from murdering people; harboring disdain in your heart is like committing murder;
  • It’s not enough to refrain from committing adultery; lusting after a person in your heart is like committing adultery.

He said more than that, but you get the point. So, it’s as simple as loving God and neighbor. At the same time, it’s as difficult as controlling what is in your heart!

To say that Jesus went easier on people is to ignore these things that he said. At the same time, Jesus confronted the men who wanted to stone the woman caught in adultery and saved her. He said he didn’t condemn her (though he also told her, “Go and sin no more.”)


What in the world is going on? If it seems difficult to sort out what is going on here, join the club.

Black offers one explanation in the video. He says God relates to people differently at different times, just as a parent relates differently to their children at different times. Parents tend to be strict with little children, imposing lots of rules about bedtimes, eating, watching TV, playing video games, doing homework and doing chores and so on.

That relationship can get contentious at times, especially as children get older and become more difficult. After children move out of the house, though, the relationship changes. It’s not that parents think the rules were bad; rather the children become adults, and become responsible for setting their own rules.

The analogy isn’t exactly the same with God, but similar. Paul says the Law was given to us as a guardian (tutor, schoolmaster, instructor, etc.). (Galatians 3:24) The Law was given to teach us something, to lay a certain foundation of understanding. The idea that Paul probably had in mind was a stern, taskmaster, training the children up with discipline.

The taskmaster’s relationship to the children is different than a parent’s relationship. A tutor only trains the children for a time when they are young. The instructor’s job is to make sure the children learn their lessons, and that is the only focus.


A parent is always a parent and never ceases to be a parent who loves and wants the best for the children. A taskmaster doesn’t love the children like a parent does.

But, it’s more complicated than that, and this is the key. The prophet Jeremiah talked about it in the context of a new covenant this way:

“I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.” (Jer. 31:33)

This is God’s ultimate goal: that we would be receptive, willing and able to receive God’s law in us, written on our hearts.

God isn’t looking for law followers, but for children who desire to be like their father. He wants us to internalize His values and be like Him – not because we must, but because we want to!

Until Christ came, men were under the Law, but Christ came to earth in the form of a human and fulfilled the Law. He died to take the penalty for our transgression; he rose from the dead to demonstrate his authority and power over death; and he ascended to heaven, leaving the Holy Spirit as a guide and comforter for us.

The Holy Spirit is how God now writes his Law in us, on our hearts. The Law is set aside, now, with its commands and regulations. (Eph. 2:15) God is looking for people willing to receive is Spirit and internalize His character in themselves as His children.

But what does this have to do with politics?

Did Jesus Come to Fulfill the Law or to Abolish the Law?

“We were held in custody under the law, locked up until faith should be revealed. So the law became our guardian to lead us to Christ….”

Much confusion in the early church arose out of the relationship of the Law to the “good news” that we now call the Gospel (which means good news). The confusion continues today. I continue to wrestle with the tension, myself.

Two passages come to mind that seem to be directly counter to each other. They establish a paradox – a seeming inconsistency – that needs to be resolved. Compare what Jesus said as recorded by Matthew, to the instruction of Paul to the Ephesians:

Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill themFor truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven. (Matthew 5:17-20)


“But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. For He Himself is our peace, who has made the two one and has torn down the dividing wall of hostility by abolishing in His flesh the law of commandments and decrees.” (Ephesians. 2:13-14)

In one place, Jesus said he did not come to abolish the law; and, in the other place, Paul says Jesus abolished the law. Which is it?

The answer is both. If we view this apparent dichotomy as a paradox, rather than a contradiction, we can make some sense of it.

First of all, we need to consider the context. When Jesus said he did not come to abolish the law, he was talking about his coming in the flesh. Jesus was God who became incarnate. Jesus was God who emptied Himself of all that separated Himself from His creation and became part of it in the form of a human being. (Phil. 2:5-8) Thus, when God became man and came to us, He did not come to abolish the law.

We also need to look at the larger context of the Law. The Law was a covenant (an agreement) with Israel. It was given to Moses for the descendants of Abraham after He brought them out of slavery in Egypt. God was faithful to this covenant, but the people were no. They filed at every turn.

This was a problem, because God promised to bless the people based on them holding up their part of the bargain, but they failed to do that. God was true to keep His part of the bargain, but He could not be true to keep His promise to bless them because they did not keep their part of the bargain.

When Jesus made the statement that he did not come to abolish the Law, but to fulfill it, he was putting that statement into the context of time and purpose. He was saying that the purpose for which he came was to fulfill the law, and now was the time.

Jesus came to fulfill the Law in the flesh as a man. When he said on the cross, “It is finished”, he was proclaiming that he had finished accomplishing the fulfillment of the Law in his human body. He lived it out perfectly. He was obedient to it unto death.

Jesus did what no man had done. God became a man so that he could keep man’s part of the bargain, and that enabled God to keep His promise to bless mankind. God, in a sense, carried out the terms and fulfilled both sides of the covenant.

But that is not the end of the story.

How the Moorings of the Gospel Were Secured

God’s promise to Abraham was given 430 years before Moses

I have taken some time to reflect on the unity for which Jesus prayed in relation to the story of Peter & Cornelius and the tension that continued in the early church over extending the Gospel to Gentiles (non-Jews). The tension that persisted at the heart of the early Church threatened to unmoor the Gospel from its footing.

In previous articles, I reflected on the deeply ingrained nature of the belief that the Jews were God’s people. They were entrusted with the Law of Moses, and they had protected the Law God gave them for well over a 1000 years, painstakingly preserving it, passing it down from generation to generation.

They were instructed by God Himself to drive out all the inhabitants in the land God promised them, to avoid intermarrying and being corrupted by the influence of “Gentiles” to worship their gods. Thus, Hebrew descendants of Abraham avoided association with others – Gentiles – like the plague.

So intent on sticking to the script were Jews in the First Century that they didn’t recognize God when He shed his deity and came to them in the form of a man, as Jesus from Nazareth. Thus, He came to His own people, and they didn’t recognize Him!

When the Word through whom the universe was created, the Word who “was with God” and “was God”, became flesh (John 1:1-3, 14), “his own people did not receive him.” (John 1:12) “He was in the world, and the world was made through him, yet the world did not know him.” (John 1:11) On the other hand:

“But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.”

John 1:12-13

“His own” were the Jews. The “all who did receive him, who believed in his name”, were Gentiles (and Jews) who believed in what Jesus said and trusted in him. They became children of God, not because they were born into it, nor because they or anyone else desired it, but because God Himself desired them to be His children. (John 1:13)

But these things were far from clear to the early Church. Even Peter, who lived with Jesus and knew him intimately, had difficulty with the idea that the Gospel should be extended to Gentiles.

In the previous articles linked above, I summarized how God gave Peter a vision that occurred three times in a row for emphasis, including by an audible voice and the voice of the Holy Spirit, directing him to go with men who appeared just then at the door to summon him. Peter’s experience was orchestrated with an angel that visited Cornelius, a Roman Centurion, who was directed to send those men to “a man named Simon who is called Peter”. (Acts 10:5)

Peter yielded to God’s obvious orchestration of these events, and he went with the man who summoned him. When he found himself at a Roman Centurion’s home, Peter recognized God was at work. Then God poured out His Holy Spirit on the Centurion and his household to emphasize to Peter his intention to extend the Gospel to the Gentiles.

But the tradition of shunning the Gentiles would not die easy. Despite the obviously divine orchestration of events to drive home God’s intentions to Peter, Paul had to confront Peter publicly in Antioch over the issue when Jews from Jerusalem came to visit because Peter had disassociated himself from the Antiochian Gentiles. (See Galatians 2-3)

Paul encountered the same issue in Galatia where people were insisting that the Jews continue to follow the Mosaic law. In his letter to the Galatians, Paul described his confrontation with Peter. More importantly, Paul explained why the Mosaic Law no longer applied to the people of God – who now included not just the Jews, but everyone!

Progression of Revelation in the Bible Part 2

In the Bible, we see a progression from Law to the spirit of the law, and from law to grace, and the seeds of that progression are there in the very beginning.


In Progression of Revelation in the Bible Part 1, I made the point that the Old Testament Scriptures anticipate and point toward Jesus. Jesus said he was the fulfillment of the Law and the Prophets. The thrust of the Scriptures from the Old Testament to the New Testament also progresses from physical to spiritual, from law to grace. I will pick up on those themes and get into the progression from law to grace in this piece.

Before doing that, though, I am taking a short sidetrack to recall an observation I made years ago as a college freshman in a world religion class. As I as I studied (and read) the Bible for the first time in my life I realized that the fabric of the Scripture, from beginning to end, is an intricately woven tapestry. I wasn’t a believer then, but I could see (as a budding English Literature major) the incredible, unlikely harmony of the Scriptures.

I say unlikely, because the Old Testament and New Testament are a combination of writings that were penned by dozens of people and collected over a period of many centuries. All of them wrote down the revelation each one of them received from God. The “book” of the Bible would be, perhaps, the finest masterpiece of cohesive literature ever written if it were written by a single author, but it’s cohesiveness and internal integrity is all the more noteworthy by the fact that it was written by dozens of authors across a large expanse of time.

People who understand the Bible only on a surface level claim it is full of contradictions. We should hardly find it surprising if it was full of contradictions, having been written by so many people over such a long time, but the thing is: a deeper reading of the Bible reveals an uncanny, transcendent, incredibly subtle and nuanced consistency and harmony.

The intricacy and harmony of the Bible is quite stunning given its authorship: the fact that it was written by people, and not by the hand of God Himself.

And this fact led me to another thought when I first read the Bible in its sweep from beginning to end: if God is God, 1) He could reveal Himself in a way that creatures made by Him could understand His communication; and 2) He could preserve the integrity of that communication. Why? Because He is God.

I didn’t become a believer immediately at that point in my life, but I could not deny the uncanny tapestry of the Scriptures.

I recall these things as I consider the Qur’an, and the progressive nature of the two religions’ Scriptures. In the Qur’an, statements in the later sura expressly contradict and abrogate (negate) earlier sura. The later sura are also the problematic ones in which we see statements about killing infidels, etc.

In the Bible, by contrast, we see the earlier Scriptures affirmed, explained and extended in the person of Jesus. We see a progression from Law to the spirit of the law, and from law to grace, and the seeds of that progression are there in the very beginning.
