Matthew 21:20-29

20When the disciples saw it, they marveled, saying, "How did the fig tree wither at once?"

21And Jesus answered them, "Truly, I say to you, if you have faith and do not doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, 'Be taken up and thrown into the sea,' it will happen.

22And whatever you ask in prayer, you will receive, if you have faith."

23And when he entered the temple, the chief priests and the elders of the people came up to him as he was teaching, and said, "By what authority are you doing these things, and who gave you this authority?"

24Jesus answered them, "I also will ask you one question, and if you tell me the answer, then I also will tell you by what authority I do these things.

25The baptism of John, from where did it come? From heaven or from man?" And they discussed it among themselves, saying, "If we say, 'From heaven,' he will say to us, 'Why then did you not believe him?'

26But if we say, 'From man,' we are afraid of the crowd, for they all hold that John was a prophet."

27So they answered Jesus, "We do not know." And he said to them, "Neither will I tell you by what authority I do these things.

28"What do you think? A man had two sons. And he went to the first and said, 'Son, go and work in the vineyard today.'

29And he answered, 'I will not,' but afterward he changed his mind and went.
