¹⁹ Then came the disciples to Jesus apart, and said, Why could not we cast him out?

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.

²³ Jesus said unto him, If thou canst believe, all things are possible to him that believeth.

²³ 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.

⁶ Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.

¹⁴ And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:

¹⁵ And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
