1 On one of the days while He was teaching the people in the temple and preaching the gospel, the chief priests and the scribes with the elders confronted Him, 2 and they spoke, saying to Him, “Tell us by what authority You are doing these things, or who is the one who gave You this authority?” 3 Jesus answered and said to them, “I will also ask you a question, and you tell Me: 4 Was the baptism of John from heaven or from men?” 5 They reasoned among themselves, saying, “If we say, ‘From heaven,’ He will say, ‘Why did you not believe him? ’ 6 But if we say, ‘From men,’ all the people will stone us to death, for they are convinced that John was a prophet.” 7 So they answered that they did not know where it came from. 8 And Jesus said to them, “Nor will I tell you by what authority I do these things.” (Luke 20:1-8 NASB)
One of my favorite books is William Tyndale a Biography by David Daniell. I have read it at least three times. I keep revisiting it to grasp the condition of the visible Church at the time of the Reformation and how God used that to inspire men to be willing to be burned alive at the stake because they dared to put the word of God into the vernacular so common people could read it.
