What made Jesus question at Mt 21:25 a good example for Christians or was it a bad question because the Jews could not answer?
Jesus asked the question to the chief priests:
Mt 21:25 The baptism of John, whence was it? from heaven, or of men?..."
25 And they argued with one another, “If we say, ‘From heaven,’ he will say to us, ‘Why then did you not believe him?’ 26 But if we say, ‘From men,’ we are afraid of the multitude; for all hold that John was a prophet.” 27 So they answered Jesus, “We do not know.” And he said to them, “Neither will I tell you by what authority I do these things."
Was it wrong for Jesus to ask what he knew they could not answer because of the parameters of his question?
