12 Reasons Why Evangelism Is Important

Evangelism — sharing the Christian faith with others — is a practice many Christians hold with genuine conviction and others approach with discomfort or avoidance. The theological case for its importance, however, is clear: the New Testament treats it not as a specialty calling for particularly bold personalities but as the natural overflow of genuine faith and the central mission of the church. These 12 reasons trace that case across its theological, relational, social, and personal dimensions.

Because of the Commission and Command

1. Jesus commanded it directly. The Great Commission in Matthew 28 — “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you” — is one of the clearest commands in the New Testament. For Christians who take biblical authority seriously, the importance of evangelism requires no further justification than the fact that Jesus explicitly told his followers to do it.

2. The early church treated it as foundational. The book of Acts records the early Christians as constantly, and often at significant personal cost, sharing their faith with anyone who would listen — in synagogues, in public squares, in homes, and before authorities. This was not the activity of a few unusually bold personalities; it was the basic identity of the early Christian community. The church’s origin story is an evangelism story.

3. The gospel is described as news — and news is meant to be shared. The word “gospel” means “good news.” News, by its nature, is shared. The New Testament writers consistently describe the announcement of Jesus’s life, death, and resurrection not as a private spiritual practice but as a public proclamation — something too significant to keep to oneself.

Because of the Stakes Involved

4. Christian theology holds that eternal consequences are real. If Christian belief is true — that Jesus is the way, the truth, and the life, and that faith in him has consequences for eternity — then sharing that truth with people who have not heard or considered it is an act of genuine love and urgency. The theological framework of evangelism is inseparable from a view of what is ultimately at stake for human beings.

5. People who don’t know the gospel cannot respond to it. Romans 10 poses the question directly: “How are they to believe in him of whom they have never heard?” Evangelism is important because the opportunity to respond to the gospel requires someone to bring it. The responsibility of those who have heard extends, in Christian understanding, to those who have not.

6. The urgency of life’s uncertainty. Christianity has always taken seriously the brevity and uncertainty of human life. The person you have the opportunity to share faith with today may not have the same opportunity tomorrow. This is not meant to generate manipulation or pressure, but it is a genuine motivator within a theological framework that takes both life and eternity seriously.

Because of What the Gospel Does for People

7. The gospel transforms lives. Christians who have experienced genuine transformation — from addiction, from destructive patterns, from despair, from a self-centered orientation toward life — have a natural motivation to share what made the difference. Evangelism at its best is not abstract theological argument but the testimony of changed lives, which is both compelling and deeply personal.

8. The gospel brings genuine hope to suffering people. In a world of loss, disappointment, and mortality, the Christian message offers hope that is grounded in something beyond circumstances — the resurrection of Jesus and the promised renewal of all things. Sharing this hope with people who are suffering is not an imposition; at its best, it is one of the most loving things a person can do.

9. The gospel creates and sustains community. The church — the community of faith — provides belonging, mutual support, shared meaning, and structured compassion that benefits people’s lives regardless of prior belief. Evangelism that invites people into this community invites them into something with immediate, practical benefits, not only ultimate ones.

Because of What It Does for the Evangelist and the Church

10. Sharing faith deepens one’s own faith. The discipline of articulating what you believe to someone who does not share your assumptions forces clarity, engagement with objections, and a deeper personal ownership of belief. Christians who evangelize consistently report that doing so strengthens and deepens their own understanding of and commitment to the faith they are sharing.

11. The church grows through evangelism. Historically, Christian communities that prioritize sharing their faith with outsiders grow; those that become internally focused tend to contract over generations. Church growth is not an end in itself, but a community that is not welcoming and sharing with outsiders is not embodying the outward orientation that characterized the early church.

12. Evangelism is an expression of love, not of judgment or superiority.

The distortion of evangelism — when it becomes aggressive, manipulative, culturally imperialist, or contemptuous of the person being addressed — is a betrayal of the thing itself. Authentic evangelism in the New Testament tradition is the humble, honest, hopeful sharing of something you genuinely believe is good — not because you are superior to the person you are speaking to, but because you are not. It is saying: this changed my life, and I think it might be true, and because I care about you, I want you to know. That is not imposition. That is love in action.
