What Is a Saint in the Bible?

What Is a Saint in the Bible?

Some people feel uncomfortable calling themselves saints. Catholic tradition has made the word sound like a status reserved for a small number of extraordinary Christians, while much of Protestant religion has trained believers to introduce themselves as “sinners saved by grace.” Paul uses different language.

To Paul, a saint is a person who is holy to God. He does not use the word only for Christians who have reached an unusual level of maturity. He addresses believers as saints even when they still need correction, even when sin is present, and even when their understanding is incomplete. The identity comes from belonging to Christ, not from earning a religious rank.

We also see the language of holy ones among the faithful under the Old Covenant. Not everyone in national Israel served Yahweh by faith. There was a faithful remnant. Under the New Covenant, everyone who receives Christ by faith belongs to His body and is holy to God. What had marked out the faithful remnant now belongs to every person in Christ.

That is why Christian identity matters so much. My broader study, Your Identity in Christ Is More Than a Position, develops that larger question. Here the point is narrower: Paul does not begin Romans by reminding believers that they are sinners. He reminds them that they belong to Jesus Christ and are called saints.

Romans 1 also connects this identity with God’s call. In What Does It Mean to Be Chosen by God?, I look more closely at Paul’s language of being called and chosen. In this passage those ideas meet: the people called to belong to Jesus are the same people Paul calls saints.

A Saint Can Still Struggle With Sin

Calling a Christian a saint does not mean God has become blind to behavior. It means He has changed who that person is. A saint can still sin, sometimes badly, but sin no longer tells the truth about the believer’s identity before God.

That difference is important. If I still define myself by the old master, I will misunderstand both grace and Christian living. Paul says that the old self was crucified with Christ in Romans 6:6, that God is no longer counting our trespasses against us in 2 Corinthians 5:19, and that anyone in Christ is a new creation in 2 Corinthians 5:17. Those are not descriptions of God pretending the old person behaves better. They describe something God has actually done.

From Slaves of Sin to Slaves of Righteousness

Paul takes the question directly in Romans 6:15–18. If we are no longer under law but under grace, should we sin? His answer is “By no means.” He then describes believers as people who were once slaves of sin but have become obedient from the heart and, having been set free from sin, have become slaves of righteousness.

“But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed, and, having been set free from sin, have become slaves of righteousness.”
Romans 6:17–18 ESV

Notice the movement in Paul’s language. He does not say, “You are still slaves of sin, so try harder to behave like something else.” He says they were slaves of sin and now they are slaves of righteousness. Grace does not leave the believer under the old master.

I understand Paul’s “obedience from the heart” here as the same kind of obedience of faith he introduced in Romans 1. At salvation our eyes were opened. We began to see sin the way God sees it, and we received a new heart toward Him. We can ignore that truth for a time, but we cannot make the old slavery our identity again.

Your Body Is the Temple of the Holy Spirit

The church in Corinth gives us one of the clearest examples that “saint” does not mean “Christian who never sins.” The Corinthians had many serious sin problems, including sexual immorality, yet Paul still addressed them as saints. His correction came from their holy identity rather than from denying it.

“Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.”
1 Corinthians 6:19–20 ESV

We were bought with a price. We have been set free from the old master, and the Spirit of God now lives in us. Think about the significance of that. Under the Old Covenant, the temple was holy because it belonged to Yahweh and was associated with His presence. Paul now uses temple language for the believer’s body.

That gives Christian holiness a very practical meaning. You are holy to God now, and sin does not fit the person you have become. Sin is like a virus. The fact that the body can survive a virus does not make the virus healthy. In the same way, grace does not make sin good for a saint. Sin works against the life we were made to live.

Another way I put it is that the new self runs on different fuel. We were made to live for Christ. When we try to fuel that life with sin, selfishness, fear, or old religious bondage, we should not be surprised when it troubles us. The Spirit living in us is not evidence that we have graduated beyond needing God. He is the Counselor who continually directs our attention back to Christ. That union is explored further in Christ Lives in Me?

Grace Trains Saints to Live Differently

Freedom from law is sometimes treated as if it must produce carelessness. Paul teaches the opposite. Grace frees us to serve God from the heart rather than trying to create holiness through a system of commandments.

Romans 12:2 tells believers to be transformed by the renewing of their minds. Titus 2:11–12 says the grace of God trains us to renounce ungodliness and worldly passions and to live self-controlled, upright, and godly lives. Grace is not only the announcement that our sins are forgiven. Grace teaches us how to live as people who already belong to God.

Freedom Does Not Mean Aimlessness

That does not make discipline bad. We need structure in our lives because that is how we are designed. The difference is that we do not need 613 commandments in order to worship our Lord. We need desire, truth, and the Spirit’s guidance. When we are lost and need direction, we have a Counselor. God can also work through brothers and sisters who help us see clearly, but the Christian life is not handed over to an institution to manage our standing with God.

This is where religious systems can create real confusion. A church can say salvation is by grace and then make daily fellowship with God depend on religious performance. The believer is told to get right with God through prescribed behavior, attendance, giving, confession, or whatever rules the system has attached to spiritual acceptability. That creates the kind of contradiction I address in The Antidote to Christian Cognitive Dissonance.

I do not promote freedom in Christ as freedom from any desire to live a holy life. Just the opposite. We are free to serve and worship our Lord in ways that come from a sincere heart. We do not have to make ourselves holy enough to approach Him. We are His saints, His Spirit lives in us, and that changes the starting point completely.

A Saint Does Not Fall Out of Fellowship With God

One of the strongest implications of this identity is fellowship with God. The gospel of grace brought believers into a perfect fellowship with Him. Not perfect fellowship with every other person, and not perfect behavior, but a reconciled relationship with God that is not turned on and off by our performance.

As we move through Romans, notice that Paul never tells a Christian that sin has put them out of fellowship with God and that they must work their way back in. Paul describes his ministry as a ministry of reconciliation. Christ did not reconcile us to the Father only until the next failure. Being in fellowship with God is where a saint resides.

That is why I reject the teaching that Christians move in and out of fellowship with God. Can You Lose Fellowship with God? develops that argument directly. When we fall into sin, God does not turn His back on His children. That may be the very moment we most need to remember that His Spirit is still living in us.

The same issue is behind the common use of 1 John 1:9 as a Christian self-cleansing formula. I do not believe John wrote that verse as instructions telling Christians how to restore broken fellowship. I believe the passage is dealing with Christ-rejecting Pharisees and others denying the truth about sin and Christ. Is Confession of Sins Required for Forgiveness? works through that question in detail.

This does not make sin harmless. It removes the false idea that our sin account is reopened every time we fail. Christ reconciled that account. Sin can still damage us, distract us, wound others, cloud our conscience, and pull our attention away from the life we were made to live. None of those consequences require God to abandon His saint.

What Changed Under the New Covenant?

The God of the New Covenant is the same God revealed under the Old Covenant. Yahweh has not changed. What changed is what Christ accomplished for those who believe and the benefits His people now receive through His finished work.

The faithful before the cross were saved by faith in what God had promised to do. They trusted what was coming. But they had not yet been crucified with Christ, made new creations through His completed death and resurrection, reconciled through that finished work, or given the permanent indwelling of the Spirit in the New Covenant sense Paul describes.

Their salvation was secure, but their relationship with God did not include the perfect fellowship New Covenant believers now enjoy. Sin still stood in the way of that relationship, sacrifices continually reminded Israel of sin, and the Spirit did not permanently dwell in every faithful person as our Counselor. Galatians 3:25 captures the change: “Now that faith has come, we are no longer under a guardian.” Paul is not saying faith did not exist before Christ. The faithful believed God would do what He promised. We believe God did it.

The New Covenant began at the cross. Its benefits were distributed after the resurrection and from Pentecost forward as the Spirit was given. Acts records the transition as people came into the reality Christ had accomplished. Reconciliation and the Spirit’s indwelling belong together in the New Covenant life.

This is why grace is bigger than salvation. If grace only secured a future destination while leaving us to cleanse ourselves and maintain our own relationship with God, then very little would have changed in our life with Him. Christ did something much bigger. He reconciled us, gave us His Spirit, and made His people holy.

The Law’s covenantal authority was removed through Christ’s work at the cross. The old guardian does not define the saints of the New Covenant. If you want to work through that covenant change more fully, begin with What Is the New Covenant?

Live Like Who God Says You Are

Paul’s answer to sin is never to pretend it does not matter. His answer is to remember who we are and walk accordingly. Galatians 5:25 says, “If we live by the Spirit, let us also walk by the Spirit.” Ephesians 4:30 tells us not to grieve the Holy Spirit of God, by whom we were sealed for the day of redemption.

Those verses hold identity and conduct together. The Spirit who seals us is also the Spirit we can grieve. Our behavior does not unseal us, but neither is it meaningless. When we turn toward what is unholy, we are acting against the life and guidance already present within us.

Keep a Clear Conscience

Jesus said that where our treasure is, there our heart will be also in Matthew 6:19–21. I see that as a question of focus, not merely money. As saints, our life is Christ. Sin steals attention, energy, and clarity. It can fill the mind with guilt and make prayer harder, not because God has withdrawn from us, but because we are distracted from the One who never left.

Paul valued a clear conscience. In Acts 23:1 he could say that he had lived his life before God in all good conscience up to that day. A conscience is not automatically trustworthy. It must be trained by truth. But a conscience trained by grace helps us recognize when something does not fit who we are.

There is always a fresh start with God. Poor decisions can bring painful consequences in these mortal bodies, and we should never pretend otherwise. But the Father is not waiting for His saints to earn their way back into His presence. He is already there. The Spirit is already in the temple.

So return to Paul’s opening words and ask the question again: What is a saint in the Bible? A saint is someone who belongs to God and is holy to Him. That identity is not a reward for getting everything right. It is what God has made the believer in Christ. Paul was honest about the failures of his brothers and sisters, but he was also honest about who they were to God. We should be just as honest about ourselves.
