Our reasons for believing Jesus existed and also that He was who He claimed to be - the God who came down - are the same reasons for believing any fact of history: the documentation is substantial and it passes all the tests of historical reliability. Scholars - both liberal and conservative - overwhelming agree that Jesus of Nazareth was a man of history and the Gospels, on the main, tell His story accurately.
Greg KouklMost Christians who've been around for a while have their Story in bits and pieces, but have never seen how powerful it really is when assembled as a whole. I want them to see how well it fits together and how it offers tremendous explanatory power regarding the world as we actually find it. I want them to see how it resolves the problem of evil, and why God's solution - the God/man Jesus - is the only solution.

Greg KouklTwo things have been bothering me for a long time. The first is the tendency of people in general - and that includes Christians - to "relativize" religion. Any religious belief is only "true for," so to speak - true for you or true for me or true for those people on the other side of the world. Second, I've been bothered by how poorly believers understand their own Story. They have bits and pieces, of course, but they're missing enough that they can easily become prey to ideas that sound spiritual, but end up being foolishness in the end.
