Repentance, Faith, and the New Birth: What’s the Connection

In This Article

I’ve sat across from a young man in a church office who looked me dead in the eye and said, “I believe in Jesus. Why isn’t that enough?” It’s a fair question. It’s also one of the most misunderstood questions in the church today.

Somewhere along the way, a lot of believers were taught that faith is a single moment – a decision, a prayer, a raised hand at an altar call – and that’s the whole story. But when you actually walk through the book of Acts, you find something different. You find a pattern. Repentance, faith, and the new birth aren’t three separate events competing for attention. They’re three parts of one work God does in a person.

Faith Is Where It Starts, Not Where It Ends

Faith gets you to the door. It doesn’t walk you through it.

Hebrews 11:6 says without faith it’s impossible to please God – that whoever comes to Him must believe He exists and that He rewards those who diligently seek Him. That’s the starting line. Faith is what makes a sinner willing to listen to the gospel instead of walking away from it.

But here’s what I tell people in premarital counseling, membership classes, and every new believer I’ve ever mentored: faith that stops at belief is faith that stops short. James put it bluntly – even the devils believe, and tremble (James 2:19). Believing facts about Jesus isn’t the same as being born again. Faith is the engine. Repentance and the new birth are where that engine actually takes you somewhere.

Repentance Is Faith Doing Something About Itself

When Peter stood up on the Day of Pentecost and preached that first apostolic sermon, the crowd didn’t ask him a theological question. They asked, “What shall we do?” (Acts 2:37). That question is what real faith produces – conviction that demands a response.

Peter’s answer wasn’t “just believe harder.” It was specific: “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost” (Acts 2:38).

Repentance is faith turning around. It’s not just feeling bad about sin – plenty of people feel bad about sin and keep living in it. Real repentance is a change of direction. It’s the prodigal son coming to himself in the pig pen and getting up to go home (Luke 15:17-18). You can’t manufacture that with willpower alone, and you can’t fake it in front of God. It’s faith proving itself real by moving.

I’ve watched people repent in a church service with tears running down their face, and I’ve watched people repent quietly, alone, weeks after they first heard the gospel. It doesn’t always look the same. But it always moves in the same direction – away from self, toward obedience.

The New Birth Is Where Faith and Repentance Land

Here’s where a lot of church background gets it wrong: the new birth isn’t a metaphor for “feeling different” after a decision. Jesus told Nicodemus plainly, “Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God” (John 3:5).

Water and Spirit. Two elements. Not optional extras – the actual new birth experience.

That’s why Peter’s Acts 2:38 sermon lines up perfectly with John 3:5. Repentance addresses the heart. Baptism in the name of Jesus Christ (not as a ritual, but as an act of obedient faith) addresses the water. And the infilling of the Holy Ghost, evidenced the same way it was on the Day of Pentecost, addresses the Spirit. Three pieces, one new birth – and none of them are decoration. Each one is doing something faith alone can’t do on its own.

This is exactly what I unpack more fully in Understanding the New Birth – because I’ve found that most people haven’t rejected this truth. They’ve simply never had someone sit down and walk them through it slowly, the way Philip did with the Ethiopian eunuch on that desert road (Acts 8:35-38).

Why This Connection Matters for Where You Are Right Now

Maybe you’ve been sitting in church for years, and somewhere in the back of your mind you know you believe – but you’ve never actually repented of something you’re still holding onto. Or maybe you repented once, cried at an altar, and never went any further with obedience.

Faith without repentance stalls. Repentance without the new birth is incomplete. And a “new birth” experience without genuine faith and repentance underneath it is just religious activity. God designed these three to work together, not to be picked apart and served individually like items on a menu.

If you’re a young believer trying to sort this out, don’t rush past the process to get to a feeling. If you’re a leader discipling someone new, don’t hand them a shortcut version of the gospel because the full version feels like too much to explain in one sitting. This is exactly the gap Operation Close the Back Door exists to close – helping people not just walk through the door of salvation, but actually stay rooted once they’re inside it.

A Few Honest Next Steps

  • If you’ve never truly repented – not just felt sorry, but turned – start there today. It doesn’t require a stage or a special moment. It requires honesty with God.
  • If you’ve repented but haven’t been baptized in the name of Jesus Christ for the remission of your sins, ask a leader you trust to walk you through it.
  • If you’ve done both but have never sought and received the infilling of the Holy Ghost, don’t assume it already happened by default. Seek it the way the early church did – earnestly, and together with other believers (Acts 1:14, 2:1-4).

Not exactly. Feeling sorry is emotional; repentance is a decision to change direction. Judas felt sorry (Matthew 27:3-4) but never repented. Real repentance produces a changed life, not just a guilty conscience.

Yes – and that’s the point of this whole discussion. Faith is necessary, but Scripture is clear that faith moves a person toward repentance and the full new birth experience of water and Spirit. Stopping at belief alone leaves the work unfinished.

Because that’s the pattern the apostles consistently followed throughout the book of Acts (Acts 8:16, 10:48, 19:5) in obedience to Jesus’ own instruction in Matthew 28:19, understanding “Father, Son, and Holy Ghost” as the titles fulfilled in the one name of Jesus Christ.

The New Testament pattern is consistent: those who received the Holy Ghost spoke in other tongues as the Spirit gave them utterance (Acts 2:4, 10:46, 19:6). It’s a specific, recognizable evidence – not a vague feeling.

Building Men and Women of Character: Developing Your Pieces

In God’s Chess Game of Life, undeveloped pieces remain trapped in their starting positions, unable to fulfill their strategic potential. Character development is God’s method of moving each believer from their initial square into positions of maximum kingdom effectiveness.

From Potential to Power Every chess piece begins with inherent abilities, but those abilities mean nothing until properly developed. A bishop stuck behind pawns cannot influence the diagonal. A knight hemmed in by its own pieces cannot reach its target squares. Similarly, believers possess God-given gifts and callings, but without character development, these remain dormant potential rather than active power.

Strategic Positioning Through Trials Master chess players develop pieces through calculated moves that may initially seem difficult or uncomfortable. God uses a similar strategy in our lives. Financial pressures teach stewardship. Relationship conflicts develop patience and forgiveness. Leadership challenges build humility and wisdom. Each trial is a strategic move designed to position your character for greater kingdom impact.

Coordinated Development In chess, pieces are developed in coordination with each other, not in isolation. Character building happens best within Christian community. Iron sharpens iron as believers challenge each other toward holiness, accountability partners provide strategic support, and mentors guide younger believers through developmental moves they’ve already mastered.

Maximum Board Control Well-developed pieces control more squares, influence more territory, and create more opportunities for strategic advancement. Believers with mature character possess greater spiritual authority, influence wider spheres for God’s glory, and open doors that remain closed to undeveloped Christians.

The Ultimate Goal Character development isn’t about perfection—it’s about positioning. God isn’t trying to make you flawless; He’s strategically moving you into a position where your unique combination of gifts, experiences, and character can deliver maximum impact for His kingdom.

Strong character equals strong position. Strong position equals kingdom influence.
