Mark 11:21-23

And Peter calling to remembrance saith unto him, Rabbi, behold, the fig tree which thou cursedst is withered away. And Jesus answering saith unto them, Have faith in God. Verily I say unto you, Whosoever shall say unto this mountain, Be thou taken up and cast into the sea; and shall not doubt in his heart, but shall believe that what he saith cometh to pass; he shall have it.
