Mark 11:20-25

And when they passed by in the morning, they saw that the fig tree had dried up from the roots. And Peter, remembering, said to him, "Master, behold, the fig tree that you cursed has withered." And in response, Jesus said to them: "Have the faith of God. Amen I say to you, that whoever will say to this mountain, 'Be taken up and cast into the sea,' and who will not have hesitated in his heart, but will have believed: then whatever he has said be done, it shall be done for him. For this reason, I say to you, all things whatsoever that you ask for when praying: believe that you will receive them, and they will happen for you. And when you stand to pray, if you hold anything against anyone, forgive them, so that your Father, who is in heaven, may also forgive you your sins.
