What did Jesus say you can do if you have enough faith and don't doubt?

Kill fig trees and move mountains into the sea

(And anything else you can think of)

Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.

And all things, whatsoever ye shall ask in prayer, believing, ye shall receive. Matthew 21:21-22
