Two events produced this post. The first event happened a few years ago and lasted over a three or four-year time period. The second event happened yesterday. Both events involved atheists attending church and overhearing worship during the teaching time. Both events continue to teach me valuable lessons about preaching.

First, atheists listen more critically to what we say than our faith-family. In this way, in a small way, I feel what Timothy Keller of Redeemer Presbyterian feels about preaching in New York City. He said he always has to make sure he has his facts right in NYC because he knew his listeners will verify his words.

My two atheists–one regular attender and one, one-Sunday visitor–listened more closely than most regular attending Christians. It means I have to pay attention to my facts during illustrations (I find that’s the time I’m most apt to misspeak). But actually, having experienced atheists in the house has made me realize how important it is for me to do my homework. I don’t want to take advantage of Christian listeners who are not as critical listeners. I don’t want to lead them astray with false data.

Second, my interaction with the two men helped me realize that our Christianity rests on faith that God’s revelation explains the reality of our world. I’m currently reading, Belief Without Borders: Inside the Minds of the Spiritual but not Religious, by Linda A. Mercadante.

Over and over again I’m reading excerpts of people believing that human beings are basically good and that they will do the right thing given enough education. Very different perspective than the anthropology of Scripture. I was challenged to continue to make it clear that God’s Story is our story. We believe that what God says in His Word is reality. We continually assess whether the lives we’re living match the reality of God’s Word.

Third, my time with the self-proclaimed atheists, both of which left the Christian faith, confirmed for me that no apologetical skill will turn a committed atheist into a committed Christian. I am responsible to preach the Word. Apart from the Spirit of God, I can’t force someone to believe God’s Word is real.

I remember hearing Dr. Norman Geisler, one of my former professors at Dallas Theological Seminary in the ’80’s say, “Apologetics is effective in helping a person who’s on the fence.” These two atheists, one of which is my friend, are not on the fence. And my best attempts at being an apologist will not win the day.

(Some readers might be interested in learning that the well-known Yale Old Testament Biblical Theology professor, Brevard Childs, once wrote me a letter stating that he felt that an emphasis on apologetics was detracting from the preaching of God’s Word.)

Anyway, there you have it: what I’m learning about preaching from atheist attendees.

Preach well so God receives glory in the Church and in Christ Jesus (Ephesians 3:21).
