4:17(As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were.

1:5If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.

1:6But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.

1:7For let not that man think that he shall receive any thing of the Lord.

1:8A double minded man is unstable in all his ways.

17:20And 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.
