What makes Christianity different from other beliefs? Why the Christian God?
My suggestion is to go back to the web site, click on power points, and begin looking at some of the presentations available there. The ones I suggest are the ones titled Faith That Answers the Hard Questions, A Defense of Christian Theology, Apologetics and World Religions and Christianity and other World Views. Also, if you go to the "store" at the web site there are a couple of audios I suggest. downloading the recording "Christianity and World Religions" in the other religions category as well as any or all of the audios in the world view section of the "store." This should give you a lot to go on, but if you still have specific questions after that, please contact me again with a more specific question.
