20  And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

  6  Wherefore, we search the prophets, and we have many revelations and the spirit of prophecy; and having all these witnesses we obtain a hope, and our faith becometh unshaken, insomuch that we truly can command in the name of Jesus and the very trees obey us, or the mountains, or the waves of the sea.

  24  And he knoweth their prayers, that they were in behalf of their brethren. And he knoweth their faith, for in his name could they remove ^bmountains; and in his name could they cause the earth to shake; and by the power of his word did they cause prisons to tumble to the earth; yea, even the fiery furnace could not harm them, neither wild beasts nor poisonous serpents, because of the power of his word.

  30  For the brother of Jared said unto the mountain Zerin, ^aRemove—and it was removed. And if he had not had faith it would not have moved; wherefore thou workest after men have faith.
