Answering the Hard Questions Part 1

We've all heard the questions - How can you prove God really exists? How do know Christianity is the one, true religion? How can you be sure Jesus is the only way to God? Is there any proof the Bible is real? Even if the Bible is real, how can you possibly know it's is actually the Word of God? Why are there so many Bible translations? Why do the translations sometimes contradict each other or have extra books in it? Can we effectively answer and defend our beliefs on this stuff? We should to be able to, because as 1Peter chapter 3 tells us, every Christian should be an apologist.
