Matthew 21:20-22

And when the disciples saw it, they marvelled, saying, How did the fig tree immediately wither away? And Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do what is done to the fig tree, but even if ye shall say unto this mountain, Be thou taken up and cast into the sea, it shall be done. And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
