How do I share the gospel with atheists?

from the old testament

• Believers can point to the complexity of creation as proof for a Creator. As David wrote, "The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge" (Psalm 19:1-2).
• Some atheists reject God because of the suffering they see in the world. In their view, an all-loving, all-powerful God cannot exist because if He did, suffering wouldn't exist. But the very fact that atheists can point to "wrongs," means there must be a standard of "right," a truth that dismantles their objection. Theists understand that God's holy nature is the standard of objective moral values and duties (Deuteronomy 32:4).

from the new testament

• Christians can point atheists to evidence for God in Creation. Paul wrote, "For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse" (Romans 1:19-20).
• Believers should discuss with atheists the historical validity of Christianity. Biblical evidence of Jesus' crucifixion (Matthew 27:35–37; Mark 15:24–26; Luke 23:33–34; John 19:16–18) is supported in secular sources (e.g., Tacitus, Josephus). Eyewitness accounts of the empty tomb (Matthew 28; Mark 16; Luke 24; John 20; 1 Corinthians 15:6) serve as evidence for the resurrection.
• How believers interact with atheists is as important as what they say. Social media discussions of God often devolve into hostile sniping, but Christians should take care to share the gospel "with gentleness and respect" (1 Peter 3:15). If the atheist reacts with hostility or mockery or isn't arguing in good faith, it's fine to disengage (Matthew 10:14).
• A believer's life is often the most powerful testimony to the truth of the gospel. Jesus told His followers, ". . . let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven" (Matthew 5:16).
• No one is responsible for someone else's conversion, though. Atheism is often a heart problem rather than a head problem. As Jesus told Nicodemas, "And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil" (John 3:19). We can and should share the truth with atheists and pray for them, but only the Holy Spirit can change their hearts (Titus 3:5).

implications for today

Have you heard the joke about the atheist stranded on the side of the road in a blizzard who prays, "God, if you really exist, please rescue me from this"? A minute later, a car pulls up, and the driver gives the atheist a ride home. The atheist says, "Thanks for your help. I asked God to rescue me. He didn't, which shows He doesn't exist. Good thing you showed up!"

Sometimes, the truth is so obvious that you have to want to ignore it to miss it.

Many people respond to the gospel the same way. God places Christians in their lives, answers questions, provides evidence of His grace, and lovingly calls them to Himself—yet they explain it all away. But that should never discourage us from sharing Christ—even to someone who claims there is no God.

Jesus commanded His followers to proclaim the gospel because only God can open blind eyes and soften hard hearts. The apostle Paul once hunted Christians and approved of their deaths, yet God transformed him into one of history's greatest missionaries. No one is beyond God's reach. Our responsibility isn't to change hearts—that's God's work. Our responsibility is to faithfully deliver the message and trust Him with the results.
