 Im writing this for you, my good friend Thiofilus. A lot of great things happened here, and the people that saw those things happen told everyone what they saw, and a lot of people wrote down those stories that they heard. After that, I read those stories, and I talked to the people that saw those things, and I checked up on everything they said, right from the start. So now I am carefully sorting out those stories, and I am writing them in this book for you.
