When I write something for the Lord and the atheists appear to refute the words, I think it is rather humorous.

“Sir. If what I say is untrue, foolish, and useless things then why do you take the time to respond to me?  Do you write letters to the author of Spongebob also?  Do you stand on the street corner and cry out against false advertising?  Has it even entered your mind as to why you despise the teachings of Christ so much?
