Mark 11:20-24

The next morning as they passed by the fig tree he had cursed, the disciples noticed it had withered from the roots up. Peter remembered what Jesus had said to the tree on the previous day and exclaimed, “Look, Rabbi! The fig tree you cursed has withered and died!” Then Jesus said to the disciples, “Have faith in God. I tell you the truth, you can say to this mountain, ‘May you be lifted up and thrown into the sea,’ and it will happen. But you must really believe it will happen and have no doubt in your heart. I tell you, you can pray for anything, and if you believe that you’ve received it, it will be yours.
