Why Do Christians Need So Much Reminding to Share the Gospel?

If you've spent any time in church, you've heard it — the pastor urging, pleading, sometimes even begging the congregation to go out and share their faith. Sermon after sermon, conference after conference, the message rings out: Go and make disciples. Books are written about it. Entire ministries are built around it. And yet, week after week, the same reminder needs to be given.

It raises an honest question: Why?

Why does the most transformative truth a person could ever receive — the good news that God loves them, that Jesus died for them, that forgiveness and eternal life are freely available — need such relentless promotion among the very people who believe it? Shouldn't it be the most natural thing in the world for someone who has been rescued to tell others about the rescue?

The answer, as it turns out, is deeply woven into the fabric of Scripture itself. The Bible doesn't just command evangelism — it anticipates our reluctance, addresses our forgetfulness, and builds an entire system around the assumption that God's people will need to be reminded, redirected, and re-commissioned again and again.

The Bible Is a Book of Reminders

One of the most striking features of Scripture is how repetitive it is — on purpose.

Consider the book of Deuteronomy. The very name means "second law." It is essentially Moses standing before the Israelites and re-preaching everything God had already told them in Exodus, Leviticus, and Numbers. Why? Because they were about to enter the Promised Land, and God knew they would forget. He didn't trust that one telling would be enough. He built repetition into His revelation.

The apostle Peter understood this principle well. In his second letter, he wrote: "Therefore I intend always to remind you of these qualities, though you know them and are established in the truth that you have. I think it right, as long as I am in this body, to stir you up by way of reminder" (2 Peter 1:12–13). Notice — Peter isn't reminding them because they don't know the truth. They do. They're "firmly established." He reminds them because knowing and remembering are two very different things.

Paul expressed the same idea to the Philippians: "Finally, my brothers, rejoice in the Lord. To write the same things to you is no trouble to me and is safe for you" (Philippians 3:1). Repetition isn't a failure of communication. It's a safeguard against a wandering heart.

The entire rhythm of Israel's worship was built around this. The Passover meal, celebrated every year, existed so that each generation would retell the story of God's deliverance from Egypt. The Sabbath was a weekly reminder of God's creative power and faithful rest. The feasts, the sacrifices, the stones of remembrance set up at the Jordan River — all of it was designed for a people prone to forgetting.

If God Himself designs repetition into worship, into Scripture, and into the life of His people, it should not surprise us that pastors must repeat the call to evangelism. The problem isn't that the message is unclear. The problem is that we are forgetful.

The Human Heart Drifts

Scripture paints an unflinching picture of the human heart, even the redeemed one. Jeremiah 17:9 says the heart is "deceitful above all things." Hebrews 3:12-13 warns believers to encourage one another daily so that none are "hardened by the deceitfulness of sin." The writer of Hebrews doesn't say this hardening might happen — the implication is that without daily encouragement, it will happen.

Think about how quickly the Israelites drifted. They watched the Red Sea split open before their eyes. They walked through on dry ground. They saw the Egyptian army swallowed by the waves. And within three days, they were grumbling about water (Exodus 15:22–24). Within 40 days, they had built a golden calf and declared it the god that brought them out of Egypt (Exodus 32).

This wasn't ancient stupidity. This is the human condition. We are wired to normalize the miraculous and drift back toward comfort, fear, and self-interest.

The same pattern plays out with the disciples. Peter declared Jesus to be the Christ, the Son of the living God — and then, just verses later, rebuked Jesus for talking about the cross (Matthew 16:16–23). Thomas saw Jesus perform miracle after miracle over three years of ministry and still said, "Unless I see in his hands the mark of the nails, and place my finger into the mark of the nails, and place my hand into his side, I will never believe." (John 20:25)

If Peter and Thomas drifted, we shouldn't be surprised when we do too.

Comfort Is the Enemy of Mission

One of the most revealing passages about the early church is found in Acts 8. After Pentecost, the believers were thriving in Jerusalem. They shared meals, studied the apostles' teaching, worshipped together, and experienced powerful community. It was beautiful. It was also stationary.

Despite Jesus' clear command to be witnesses "in Jerusalem, and in all Judea and Samaria, and to the ends of the earth" (Acts 1:8), the early believers stayed put. They were comfortable. They had found a rhythm. And honestly, who could blame them? Community was rich. Worship was powerful. Why leave?

It took persecution — specifically the stoning of Stephen and the scattering that followed — to push the church outward. Acts 8:1 says "And there arose on that day a great persecution against the church in Jerusalem, and they were all scattered throughout the regions of Judea and Samaria." And then, verse 4: "Now those who were scattered went about preaching the word."

The uncomfortable truth is this: comfort and mission are often at odds. The early church didn't go until they were forced to go. And if the Spirit-filled, miracle-witnessing, apostle-taught first generation of Christians needed a push, how much more do we?

This is why pastors spend so much time on the topic. Not because the congregation is disobedient or uncaring, but because the gravitational pull of comfort is relentless. We settle into our routines, our small groups, our Sunday services. We build wonderful communities of faith — but communities that can become inward-facing fortresses rather than outward-reaching mission posts.

The Spirit Is Willing, but the Flesh Is Weak

Jesus spoke these words to His disciples in the Garden of Gethsemane (Matthew 26:41), and they capture a tension every believer lives with. There is a genuine desire within the believer to obey God, to share the gospel, to live on mission. But there is also an equally real pull toward self-preservation, fear, and passivity.

Paul described this inner war vividly in Romans 7:15–19: "For I do not do what I want, but I do the very thing I hate." This is the apostle Paul — the greatest missionary the church has ever known — confessing that the gap between intention and action is real and persistent.

Evangelism sits right at the intersection of this struggle. To share the gospel is to be vulnerable. It risks rejection. It interrupts comfortable relationships. It requires us to prioritize someone else's eternal destiny over our temporary social ease. Every part of our fallen nature resists this.

Consider what evangelism actually asks of a person. It asks you to bring up the most important and most personal topic imaginable — someone's relationship with God — in a culture that considers religion a private matter. It asks you to risk being seen as judgmental, preachy, or out of touch. It asks you to care more about a person's soul than their opinion of you. That is an enormous ask of the flesh, even when the spirit is entirely willing.

We Underestimate the Stakes

Another reason the call must be repeated is that we tend to lose sight of what's actually at stake. Daily life has a way of making eternal realities feel abstract.

When you're worried about paying rent, navigating a difficult marriage, raising children, or managing your health, the idea that your neighbor needs to hear the gospel can feel distant, theoretical — something for the missionaries and the pastors. The urgency fades not because we stop believing, but because the immediate drowns out the eternal.

Jesus told a parable about a rich man and a beggar named Lazarus (Luke 16:19–31). After death, the rich man — now in torment — begged Abraham to send Lazarus back to warn his five brothers. Abraham replied that they had Moses and the Prophets; they should listen to them. The rich man insisted: "No, father Abraham, but if someone goes to them from the dead, they will repent." Abraham's response is haunting: "If they do not hear Moses and the Prophets, neither will they be convinced if someone should rise from the dead."

The point is devastating. We have the truth. We have the Scriptures. We even have the testimony of the risen Christ. And still, urgency eludes us. This is precisely why the message must be preached again and again — not because it isn't true, but because we are constantly drifting into a kind of spiritual sleepwalk where we go through the motions of faith while forgetting the fire behind it.

Even the Apostles Needed Re-Commissioning

If anyone should have "gotten it" the first time, it was Peter. He had walked with Jesus for three years. He had heard the Great Commission directly from the risen Christ. He had preached at Pentecost and seen three thousand people come to faith in a single day.

And yet, in John 21, after the resurrection, Jesus finds Peter doing something remarkable — he has gone back to fishing. Not metaphorical fishing. Literal, nets-in-the-water, back-to-the-old-life fishing. And Jesus meets him on the shore and asks him three times: "Do you love me? Feed my sheep. Do you love me? Take care of my sheep. Do you love me? Feed my sheep" (John 21:15–17).

Three times. Not because Peter didn't love Jesus, but because Peter needed to be called back. He needed to hear it again. He needed to be re-commissioned, re-focused, and re-sent.

If Jesus Himself felt the need to repeat the mission to His closest disciple — face to face, after the resurrection — then perhaps we should stop being surprised that our pastors need to do the same for us, week after week.

The "Already but Not Yet"

Theologians often describe the Christian life as living in the "already but not yet." We are already saved, but not yet perfected. We already have the Holy Spirit, but we do not yet have glorified bodies free from sin's pull. We already know the truth, but we don't yet live it out perfectly.

This theological reality explains the gap between what Christians know they should do and what they actually do. Sanctification — the process of being made more like Christ — is exactly that: a process. It takes time, repetition, discipline, community, and yes, a lot of preaching.

The writer of Hebrews addresses this directly: "And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near." (Hebrews 10:24–25)

The entire structure of church life — gathering weekly, hearing the Word preached, singing together, sharing communion — exists because we are not yet what we will one day be. We need the rhythm. We need the repetition. We need each other.

What Should We Do With This?

If the Bible itself is built on the assumption that God's people will drift, forget, and need constant redirection, then perhaps we should stop feeling guilty about it and start responding to it.

Here is what this reality calls for:

Humility. Recognize that you are not above the need for reminders. Peter wasn't. Paul wasn't. The Israelites who saw the Red Sea part weren't. You aren't either. When your pastor preaches on evangelism for the hundredth time, receive it not as nagging, but as a kindness — a safeguard for your soul.

Gratitude for pastors. The work of re-calling a congregation to mission is exhausting and often thankless. Pastors who faithfully preach evangelism are doing exactly what Peter, Paul, and Moses did. They are standing before a forgetful people and saying, "Remember."

Honest self-examination. Ask yourself: When was the last time I actually shared my faith with someone? Not argued about theology online, not posted a Bible verse on social media, but looked someone in the eye and told them about Jesus? If the answer makes you uncomfortable, that discomfort is a gift. It means the Spirit is still stirring.

Action, not just agreement. The most dangerous response to a sermon on evangelism is to nod along and do nothing. James 1:22 warns: "But be doers of the word, and not hearers only, deceiving yourselves." Agreement without action is just well-dressed disobedience.

Grace for yourself and others. The fact that we struggle with this doesn't make us failures. It makes us human, saved by grace, still being sanctified. The call is not to be perfect evangelists — it's to be faithful ones who keep showing up, keep trying, and keep listening when the pastor says, once again, "Go."

A Final Thought

There is a beautiful irony in all of this. The very gospel we struggle to share is a gospel of grace — grace for the broken, the forgetful, the reluctant, and the afraid. The same God who commands us to go is the God who knows we will hesitate. And He doesn't abandon us in our hesitation. He sends pastors to remind us. He gives us His Spirit to empower us. He puts people in our paths who are ready to hear.

The question has never been whether God's people need reminding. Of course we do. The question is whether we will listen when the reminder comes — and whether, this time, we will actually go.
