Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) Hebrews 10:23 KJV
He is unwavering and so should we be.
If 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. But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord. James 1:5-7 KJV
Doubt will route your promise. Have faith believing.
Your God is Faithful and True!
