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people inside and outside of the Christian community are unclear on what laws Christians must follow, what laws are no longer applicable, and why.

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 is what motivated someone 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 of Moses were completed, there were 613 commandments! (Though not everyone agrees on exactly what they are.)

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 laws are often more prominent 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 between Paul and Peter that threatened to divide the early church 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 summarize 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 critical.

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 Christianity.

It was the focus of almost all of Paul’s writings. It is the major theme in Romans, Galatians, Ephesians, Hebrews and the other epistles. 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.

What It Means to Be Called According to God’s Purpose

Abraham understood that God’s purposes were much greater than Abraham and Sarah, much greater than the land promised to them, much greater even than all his descendants that would populate the earth like the stars in the sky and sand on the seashore.

God calls us according to his purpose. He calls us as beings He created in His own image. He calls us as His image bearers, and He gives us the responsibility for being fruitful and multiplying and tending to the creation that He made.

We messed up His creation. We got it all wrong. We went our own ways. We sought to make a name for ourselves. We pursued our own ends.

Then God became flesh. He became a man and lived among us. He subjected Himself to the worst of our messiness. Unbelievably, He gave Himself up to us – and for us – to redeem us from our own devices. AND to redeem us for His purposes.

God invites us to become His children by accepting this great sacrifice that He made for us. He now invites us to give ourselves up to Him and to let Him take His rightful place in our lives and hearts and to make His purposes our purposes.

Sometimes, I believe, we have too small a view of God and His purposes. We tend to be satisfied to think that God merely desires to save us from ourselves, and we do not have a robust view of God’s purposes.

Thoughts on Perspective, Science and Faith

As finite beings, We have no choice put to adopt our fundamental principles on faith. We do not have the requisite perspective to have more certainty than that.

I have two blogs I maintain currently: Perspective and Navigating by Faith. Perspective and faith loosely characterize my journey over many years: trying to find perspective and understanding the value, the necessity, and the integrity of a faith grounded in reality, both observable and unseen.

Many people believe that faith is the opposite of fact and at odds with science and reason. I strongly disagree. I have come to believe that faith is inescapable for finite beings – both religious ones and non-religious ones alike – and faith lies at the core of everything we believe to be true.

I was listening to a podcast discussion recently when one of the participants said something like this: When we approach any evidence, we approach it with a perspective. This is a non-pejorative way of saying that we are all “biased”.

As finite beings we are all necessarily “biased” by our own perspective, our own experiences, our own knowledge, understanding and ability to grasp, synthesize and categorize what we know and understand. Our perspective is influenced and filtered through our location in the world, our place in the culture and society in which we live, the history that we remember, and too many other things to summarize them adequately in a short blog article.

The discussion in the podcast that prompts this writing focused briefly on the fact that we all bring assumptions to the table when we consider anything. Those assumptions, however intentionally or surreptitiously developed, are the bedrock of each of our worldviews. They are the foundations on which we stand. They are the filters through which we see the world.

Those assumptions are developed, to a greater or lesser degree, by some combination of our external influences, our internal leanings and reactions to those external influences, and our consciously or unconsciously chosen compass points we use to guide ourselves in sorting out the information we encounter.

At the most basic level, those assumptions are axiomatic. They are truths we take for granted. We cannot prove them, and we rarely question them without crisis. We are fortunate if they hold us in good stead, if they are well-enough grounded in reality and fact to be of benefit to us in our dealings with the circumstances of our lives.

If those basic assumptions are not well considered and well-grounded, we can be blown about by every wind. If they are not based in fact and an accurate grasp of the nuance of reality, they can prove little consolation or comfort in times of crisis. If they are not well-anchored in timeless truth, they can leave us adrift when we need to count on them most.

The unique perspectives in light of which finite beings approach any evidence is necessarily limited and biased because we are limited and finite beings. At best, we can only hope to orientate ourselves in the direction of truth. We don’t define truth. We don’t establish truth. We don’t’ generate truth.

This is necessarily the case with finite beings who can only approach reality from a particular location at a particular time in the context of a particular cultural, historical, and philosophical point of view.

If I was omniscient and all seeing, I could have ultimate confidence in my perspective. My perspective would be objective and factual. My perspective would be the measure of all reality.

But no human being can validly make that claim (though we may and often do think and act like we can). In all honesty and humility, we must each admit that we come at evidence from a perspective with bias born out of our own experience, cultural context, limited knowledge and limited understanding.

We don’t know what we don’t know.

As a necessary corollary to these things, which I believe with all the certainty that I can possibly ascribe to these things, we are creatures of faith. All of us. We have no choice put to adopt our fundamental principles on faith. We do not have the requisite perspective to have more certainty than that.

My conclusion in this regard is based on fact (that humans are finite beings) and “logic” or philosophy, which reasons from the fact that we are finite to conclude that our perspective is limited thereby. Because our perspective is limited, we must rely on faith in making our conclusions which, themselves, derive from the fundamental assumptions we also take on faith. We can’t escape these limitations because they are inherent in finite creatures such as ourselves.

Some people even in this modern age, however, have boldly claimed that science is the study of all the reality that exists. Further, they say, therefore, we no longer need philosophy or theology. (I have heard Neil deGrasse Tyson say this very thing.) I am going to push back on that idea in this blog post.

The Story of Abraham and Isaac Revisited: Introduction

God tests Abraham’s faith by asking him to sacrifice his son. Abraham in faith goes ahead but God intervenes to provide a ram for sacrifice instead.
Genesis 22.

Everyone in the western world has heard of the story of Abraham and Isaac. It is iconic. Even people who didn’t hear the story in Sunday school as a child have heard the story somewhere along the way in their lives. The story is a commonly referenced in literature and art, and often with negative connotations in our modern world.

Dare I say that most people have a shallow understanding of the story – even Christians? I would include myself in that category for most of my life, though I had the fortune of hearing the story and considering it for the first time, not in Sunday school, but in a college World Religion class.

The “fortune” of hearing the story for the first time in the context of an academic environment is that that I approached it first intellectually with an open mind. I approached it critically – not as in being critical of it, but as in being thoughtful about it.

Those discussions have stuck with me. We learned about the Mesopotamian world in which the story arose, including the theory that monotheism was born in that time and region (not necessarily of Hebrew origin).

I have since spent many hours thinking and writing about those things I first learned in that class about the Ancient Near Eastern world in which Abraham would have lived. I have learned other things as well, such as the apparently universal practice of child sacrifice to the gods that dominated the religious thought in that culture.

The story of Abraham and Isaac must be read in that context to understand how it fits in. We learn through the story that the God of Abraham was radically different from the gods of the Ancient Near East culture in which Abraham lived.

In Abraham’s world, every people group and community had their own gods. While each community of people had their own gods, and each god was different from the next, one thing those gods all had in common: they were unpredictable, arbitrary and capricious.

Everyone Abraham knew assumed that the gods had to be appeased, and appeasing the gods often meant sacrificing your own children to them if necessary. Abraham would not have recoiled in moral horror at the thought that God was insisting he sacrifice his son. As difficult as it might be, you didn’t argue with the gods.

We tend to focus only on Abraham’s faith, as if that is the sum and substance of the story. Faith is the Sunday school lesson, but it’s only a shallow understanding if we see nothing else in the story. Faith is merely the beginning of understanding:

“And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.”

Hebrews 11:6

Without Abraham’s faith in God, he would not have learned that God was different than other gods. Abraham’s faith was the key to learning that God was different, and Abraham’s discovery of the unique character of God is the real gem of this story – that He is not unpredictable, arbitrary and capricious like the other gods.

Abraham was a man of faith. He believed God exists, and he believed that his God was the God of gods. He believed that God could be approached; God could be trusted; and God rewards those who seek Him. Abraham was a man who sought to draw near to God, but that is only the beginning.

In the story, we see that Abraham expected God to be like the other gods he knew, but we also see that Abraham sensed something different about God. God used Abraham’s cultural understanding of the gods to show Abraham that He was different.

God is not arbitrary and capricious. He has plans for His creation. He desires to bless His creation. He desires relationship with His creation, and we (like Abraham) can engage God in that purpose by faith – by trust in God’s benevolence and good intentions toward us.

This understanding of the story will become more evident as we dig deeper in the next article: The Story of Abraham and Isaac Revisited: Here I Am. While the Sunday School version is all about Abraham’s faith, and the secular, cynical version fixates of the savage notion that a god might demand child sacrifice, the real gem of the story is that God is not like the other gods Abraham knew.


The Beginning of an “Unapologetic” Argument for God

Faith is the inevitable position of a finite being who does not know all there is to know.

I really like apologetics. I find it interesting to think about, but apologetics has limited power as a tool to convince people to believe in God. It is not a magic bullet. There is no magic argument to prove the existence of God.

When I see article titles or social media posts that make claims of proving the existence of God, I cringe a little bit. It’s a promise we can’t deliver. We really shouldn’t “go there”. I feel that we should be more honest than that.

Of course, the “promise” depends on the definition of “prove”. The Oxford online dictionary defines the word, “prove”, as follows:

  1. demonstrate the truth or existence of (something) by evidence or argument. (“The concept is difficult to prove.”)
  2. demonstrate to be the specified thing by evidence or argument. (“Innocent until proven guilty.”)

If everyone accepted and applied these definitions, perhaps, we could find more common ground. A “proof” in the first sense is just evidence or argument that demonstrates the truth of the existence of something. Whether that proof actually, definitively and absolutely provides the truth or existence of that something, is another matter. A proof in this sense is still open to judgment whether it accomplished the goal.

A proof in the second sense is similar, and the example includes a standard of proof (one that we use in criminal proceedings). This example raises a key point: Without agreement on the standard of proof, the determination whether a proof is successful in proving that point is a moving target.

The success of any evidence or argument in proving a point depends on what standard of proof is applied. Two people may apply two very different standards of proof and, therefore, arrive at two very different conclusions on the determination whether the proof was successful.

Most of the arguments between theists and atheists gloss over and fail to recognize this fundamental issue. Not only do they apply different standards of proof, they make all kinds of different assumptions, and worse: they define their terms differently. It’s no wonder the debates and discussions produce so much disagreement. They are basically talking in foreign languages to each other.

Wikipedia defines “proof” as “sufficient evidence or a sufficient argument for the truth of a proposition.” What is “sufficient” evidence, though, depends on the standard of proof that is applied. Different standards of proof will yield different results.

For instance, we generally apply different standards of proof in the American legal system in different contexts. In civil cases, the applicable standard of proof is “more likely than not”, and in criminal proceedings, the applicable standard of proof is “beyond a reasonable doubt”.

Proving a case under the “more likely than not” standard is much easier than proving a case “beyond a reasonable doubt”. The higher standard (“beyond a reasonable doubt”) is designed for criminal cases with the purpose of causing “the system” to err on the side of finding a guilty person innocent (rather than erring on the side of convicting innocent people).

At least, that is the theory. People still disagree on the outcomes of criminal cases, and innocent people are sometimes found guilty, even when applying the much higher standard of proof. I am reminded of the axiom: to err is human.

These problems of proof are inevitable for finite beings. We don’t know what we don’t know, and we are always prone to “getting it wrong”. If we don’t take that limitation seriously, we become arrogant and prideful.

Therefore, I am reminded of the propriety of maintaining humility. Even if we are certain in our own minds of the truth of a matter, we should be mindful of the human tendency to get things wrong.

This is where faith comes in. Faith, in part, is an exercise in humility. Faith is the inevitable condition of being human, and that goes for faith in the truth that science reveals and faith in the truth that the Bible reveals. Let me explain.
