Many Evangelical Christians take seriously Jesus’ command to go into all the world and preach the gospel to every creature. Every creature includes atheists.
Here is what Christians need to understand:
- Many atheists were Christians before they deconverted. In my case, I was a Christian for fifty years and I was an Evangelical pastor for twenty-five of those years. Granted, most atheists’ stories are not like mine, but many of them were raised in the Christian church and know what the Christian gospel is and what the Bible teaches.
- Many atheists have read the Bible numerous times. In fact, many atheists have likely read the Bible more than the average American Christian.
- Many atheists attended church before they deconverted. They know a good bit about Catholic and Protestant Christianity. They know what it is to worship God, pray, and live according to the teachings of the Bible. They are not ignorant of what it means to be a follower of Jesus.
- People become atheists for a variety of reasons. Often there are psychological and cultural reasons why people become atheists, but most people become atheists for intellectual reasons.
- Most atheists are not atheists because they are angry with God, mad at the church, or hurt.
Here are some evangelistic methods that will likely not work with atheists:
- Preaching at the person
- Quoting Bible verses (the atheist has likely heard the verses before)
- Giving a testimony of how Jesus saved you and changed your life (atheists place little value on subjective stories such as testimonies)
- Giving the atheist a Christian book, tract, sermon tape/CD/DVD
- The Romans Road, John Road, Four Spiritual Laws, The Way of the Master, or any other evangelistic program you have been taught
- Inviting them to church
- Friending them on Facebook
- Trying to become friends with them using friendship evangelism methods
- Threatening them with Hell
Personally, I suggest you not witness to atheists. You are likely going to be disappointed with the result. There are a lot of “other” prospects for Heaven — low-hanging fruit — who are much easier to evangelize than atheists. However, if you are certain God is directing you and the Holy Spirit is leading you to witness to atheists, I would encourage you to be all prayed up and ready to have an intellectual discussion about God, Jesus, and the Bible. Be prepared to talk about theology, philosophy, history, science, and archeology. Be prepared to give evidence for the assertions and claims you make. Saying the Bible says won’t work since atheists do not accept the authority of the Bible.

You might as well face it, if atheists refuse to accept the Bible as a God-inspired authoritative text, there is no hope of you successfully witnessing to them. You should kick the dust off your shoes and evangelize those who accept your presuppositions about God and the Bible.
Atheists are the swine in the don’t cast your pearls before swine Bible verse. Atheists are reprobates whom God has turned over to their evil desires. Atheists are followers of Satan, deaf and blind to your God and the Bible. With so many billions of other people to witness to, why bother witnessing to people who have no interest in your message, are likely to make great intellectual demands of you, and are probably not God’s elect? Be a smart fisher-of-men — go where the fish are.
