Is Merely Believing In Jesus Enough?

Jesus said that many people will say to him on the day of judgment, “Lord, Lord”, but he will tell them that he never knew them.


I follow a daily Bible reading plan every year. In most years I read through the Bible from beginning to end, but this year I am focusing on the New Testament only. Today, I came across this rather innocuous verse that prompts my thoughts:

Now when he was in Jerusalem at the Passover Feast, many believed in his name when they saw the signs that he was doing. But Jesus on his part did not entrust himself to them, because he knew all people. 

John 2:23-24 ESV‬

Though I was raised Catholic, a combination of evangelical people who shared the Gospel with me led me to a real, authentic belief in God and surrender to Jesus “as my Lord and Savior” (as the saying goes). I can’t say that I didn’t believe in God before that time (intellectually), but God didn’t mean anything to me before then. I had no relationship to God, and the existence of God carried no relevance in my life.

As a young Christian, I put great weight on simply believing in Jesus, which was what was emphasized to me. It seemed to me that believing in Jesus was all a person needed to do to be saved, and everyone who believed in Jesus was OK. I think that is still fundamentally true, but it is not the whole truth.

I was grateful, of course. Belief in Jesus changed my life! I recognized the changes deep within me, which I believe is indicative of being born again. My eyes were opened, and now I could see!

Many years later, however, it doesn’t seem quite so simple. Examples of people who go to church, and claim to be Christian, but who don’t act anything like Jesus, are legion. This hypocrisy among the people who call themselves Christian is a common reason why people say they don’t go to church any more. Many people don’t live what they believe.

Of course, we are all hypocrites to some extent. None of us live up to God’s standard. (Nor do we even live up to our own, lower standards, if we are being completely honest.)

There are differences in degrees. Some people are more like Jesus than others. The Bible acknowledges that we must all grow in our knowledge of God, and the Bible recognizes that sanctification is a process.

In my own life, I experienced some relatively instantaneous changes in me, especially in my attitudes, in what I was drawn to, and in my understanding (like a light bulb turning on). I also continued to struggle with habits of thought and action, some of which dog me still to this day.

We want simple formulas. Romans 10:9 says, “[I]f you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.” ( ESV) This literally says that believing in our hearts and confessing with our mouths that Jesus is Lord is all that is necessary for salvation.

I believe in that “formula” with all my heart. BUT – at the same time – it is is not quite so simple. Jesus said, “Many will say to me, “Lord! Lord!”

We might have a tendency to view the “Romans Road” as a kind of magic formula that makes a person a Christian, but it doesn’t exactly work like that. Anyone can mouth those words with no change in their inner reality. It’s not enough to confess with your mouth, a person must believe in his/her heart.

Anyone can confess that “Jesus is Lord”. The confession must come from a real and authentic belief in the heart that results in a change to be assured it has real substance.

This change is not something we can manufacture. It occurs organically from the inside out. The change may not even be immediately noticeable. This is because the change results from God working inside us, not by our efforts to conform, but by His regenerative work in us. It may take a while to bear fruit on the outside.

People look at the outward appearance (confession), but God judges the heart. (1 Samuel 16:7) People may claim to be Christian, especially in the United States where being Christian can provide social, political, or other capital, but that doesn’t mean everyone who claims to be a Christian is an authentic believer and follower of Jesus.

Jesus said that many people will say to him on the day of judgment, “Lord, Lord”, but he will tell them that he never knew them. (Matt. 7:22) Jesus said that some of these people will even prophesy, cast out demons, and perform miracles in his name, but, they are not true believers. (Matt. 7:23) (If you want to hear the personal stories of people who recognize that they were once “false converts”, I am providing a link to their stories here.)

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 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 to 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 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 Christianity.

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

Who Are the Righteous and the Wicked? Part III

Abraham’s faith was more than naked belief; it was belief that prompted him to act in trust in God.

“All Scripture is breathed out (inspired) by God and profitable for teaching, for reproof, for correction, and for training in righteousness….” (2 Tim. 3:16)

I was prompted in reading Psalm 1 to focus on the distinction between “the righteous” and “the wicked” in Who are the Righteous and the Wicked? Part I. As I began to dig into it, I observed that only God is righteous, and our righteousness depends wholly on our relationship to God. If we believe (trust) Him, he credits His righteousness to us. (See Part II) Abraham is our example: when he believed God, His faith in God was credited to him as righteousness. (Gen. 15:6 & rom. 4:3)

This is all very fundamental to Christianity. It might prompt us to make the assumption that people who merely believe God, believe the Bible (and go to church) are righteous. There is a fly in that ointment, however; and James identifies it in his letter.

James acknowledges that Abraham believed God, and his belief was counted to him as righteousness (James 2:23), but James digs a little deeper into what “the righteousness that comes by faith” (Rom. 3:22) really looks like. After all, even demons believe in God (James 2:19), but they aren’t righteous! The difference between the righteous and the wicked, therefore, involves something more than merely believing in God

We explored the idea that righteousness is something that flows from God, out of His very Being. It is not something God decreed, but something that God is in His very nature. Righteousness is not an abstract ideal that God lives up to; God is righteous. We don’t describe God in respect to righteousness; we know righteousness by knowing God.

It helps, perhaps, to take morality out of the equation and to look at it through a more scientific lens. Just as gravity is what it is and operates the way it operates (because that is how God created the universe), righteousness is simply what it is. Righteousness, however, isn’t something God created, like gravity; righteousness flows from the very nature and character of God.

To put it very simply: God defines righteousness by who He is, and righteousness is defined in relation to God.

Thus, we can only know righteousness in relation to God. We can’t be righteous, because only God is righteous. God credits His righteousness to us who believe (trust) in Him, but that is only the beginning.

Christians might call this being born again. We believe God; God counts us righteous; and, thus, He welcomes us into relationship with Him. A birth, however, is only the beginning.

When we dig deeper, as James did, we see a specific characteristic to the belief that Abraham by which God credited it to him as righteousness. That characteristic is something more than bare belief. Demons, who also believe, don’t have that characteristic (otherwise their belief would be credited to them as righteousness too). This characteristic is what James is getting at when he says that “faith apart from works is dead”. (James 2:26)

Abraham’s faith prompted him to action. James says that Abraham’s “faith was active along with his works”, and his “faith was completed by his works”. (James 2:22) Thus, Abraham’s faith was more than naked belief; it was belief that prompted him to act in trust in God.

Having some understanding of what makes a righteous person righteous, and what doesn’t, is essential to our relationship with God.

Faith that doesn’t prompt a person to action is not the kind of faith Abraham had; it is not the kind of faith that is credited to a person as righteousness. Faith that only prompts feelings is not the kind of faith that leads to righteousness. (James 1:19) The faith that leads to righteousness is faith that prompts a person to be a doer of God’s word. (James 1:22-25) It is faith that prompts love for God and love for neighbor, and that love is active! (James 1:26-27)

Faith that doesn’t result in a change from the core of a person’s being that emanates out into a change of heart and change in action is not the kind of faith that can be described as being born again. It is not saving faith, and it is not the kind of faith that God attributes as righteousness to people. 

The Difference Is In What We Do


These were the words I read this morning when I opened my Bible app:

“So then, as we have opportunity, let us do good to everyone, and especially to those who are of the household of faith.” (Galatians 6:10 ESV)

As I think about this exhortation from Paul, I realize that our faith is meant to be manifested in doing good. It also occurs to me that, maybe, we have gotten the emphasis wrong.

I can understand how it happened. Common people didn’t have the Scripture to read for themselves. The church had gotten corrupted by power and wealth. Priests sold indulgences and turned faith into a religion of required observances and superstitious piety.

John Wycliffe and others made Scripture available to the common people, and Martin Luther and the people he inspired rediscovered the that salvation is received by faith. It’s a matter of grace, not of works, lest any man boast.

These things were inspired by the Holy Spirit at the time, but we always flirt with the danger of settling into religious ruts that prevent us from appreciating and considering the whole counsel of God. Western Protestantism has tended for centuries to accept the stuffy air of an academic, heady faith that gets too little exercise in the “good works, which God prepared beforehand, that we should walk in them”.[1]

This is the progression: We are “saved through faith”; this is not our own doing; “it is the gift of God, not a result of works, so that no one may boast”.[2] But we can’t stop there. We have to realize the truth of the very next statement: “For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.”[3]

We are saved by faith, not by works, in order for us to do the good works God prepared for us to do.

We are saved by faith, not by works, in order for us to do the good works God prepared for us to do.

Paul’s words in Galatians and the entire thrust of Scripture suggest that the hallmark of Christian faith is the good that we do that flows out of the salvation we received by faith.
