And this is important... why?
We’ve shown you plenty of Scripture, and every time we do, you continue to move the goalposts.
I’ve also shown you that the Apostles obviously believed that Jesus’s commands to preach and teach also included writing things down, so there’s the answer to your stringent demands THIS time.
Unless you think that you know more about what Jesus was talking about than the Apostles did?
Many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught. (Luke 1:1-4)
