One site I frequent is WikiAnswers, formerly known as FAQ Farm. This is a question & answer site, but managed via a wiki, much like Wikipedia. Using the original farm analogy, questions & answers are "grown" into hopefully professional, or at least reliable, answers. Some questions, of course, can only be "answered" by giving a list of opinions. That happens often with the section I supervise, Religion & Spirituality.
Recently one user arrived and has been contributing rabidly. The person professes atheism, claiming that he was "brainwashed" in Catholic school. He, like many, feel that the only "smart" response to religion is to examine it from a logical point of view.
The problem is, God doesn't work like that. His ways are not our ways; our wisdom, compared to His, is utter foolishness. God doesn't promise to work within our own prejudices and preconceptions; rather, He wants us to learn His ways. Why? Because they're better. Because He's right.
Too many people, though, won't accept it. They choose to reject any formula other than their own. Then they expect God to meet their standards. How foolish!
This evening at our church, a fellow who leads the 18-35(ish) crowd taught about God's calling. One of the things God made me realize is that my calling isn't to convince the atheist that he's wrong. Only the Spirit of God can do that. All I'm told to do is to write the truth in love, and present the Good News to them.
I hope to be writing much more here as part of that calling.
