Mark 11:23

Truly I tell you, whoever may tell this mountain, 'Be taken up and cast into the sea,' and does not doubt in his heart, but believes that what he says is happening; it will be done for him.

For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
