Theophilus, this one’s for you. Plenty of people have written about these things. I went back to the very beginning, talked to the people who were there, checked everything, and put it in order. So you can be sure.
Many have undertaken to compose an account of the things that have been fulfilled among us, just as they were handed down to us by the initial eyewitnesses and servants of the word. Therefore, having carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught.
