Christianity is living truth, and it should be preached and defended as such. We might only be able to convince the non-believer that Christianity is plausible or believable. Our job is to provide a solid intellectual foundation to make those steps sure. Now we'll finish our discussion by outlining a way of presenting a case for Christianity. Since God created the universe and is active in His creation, there is no lack of evidence for the truth of Christianity.
Evidence is anything that can be brought to bear on the truth-claims of Scripture.
As we present evidence, we must be aware that the false presuppositions unbelievers hold about God, man, and the world might skew their evaluation of the evidences. In fact, the idea of encouraging people to evaluate Christianity makes some people uneasy. No, we aren't. We are simply recognizing that, although the Bible never hints that anyone is justified in rejecting its message, it does present witnesses to the truth, typically through historical reminders and miracles. Further, because unbelievers are made in God's image and live in God's world, they have some understanding of the truth, and we can appeal to that understanding.
