Jesus

20 When the disciples saw it, they marveled, saying, “How did the fig tree wither at once?” 21 And 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. 22 And whatever you ask in prayer, you will receive, if you have faith.”
Matthew 21:20-22
