What is Christianity?

Why did Jesus come to Earth? What is the point of this whole thing we call Christianity? Does it have anything to say to us? What does the Bible say? How do we interpret it? So many questions, I hope to provide, not answers, but even more questions. I'll try to present different perspectives, though probably not in a completely unbiased or scholarly fashion. So I'll attempt to work through quite a bit of material, hopefully improve my writing and communication skills. I'll experiment with different writing styles and perspectives. I hope this will be fun and of course comments are welcome.
