No christians beleive in God eisting they do not know it for fact. Thats why they take their leap of faith, thats what faith is beleiving in God without facts. So what are you on about? Well, actually, I also know that Christianity is true. 1. I could cite different evidence, but then we just get into our argument of "my proof v. your proof" 2. The change I have had in my heart after accepting Christ. 3. It makes sense, something rare in today's religions. 4. I can feel close to God and feel His presence when I worship Him. Christianity is about that "leap of faith" but once you've taken it, then everything falls into place perfectly. It doesn't make anysense for me. :?
