Faith

Commit your way to the Lord [roll and repose each care of your
load on Him]; trust (lean on, rely on, and be confident) also in Him and He will
bring it to pass. (Psalm 37:5 AMP)

No unbelief or distrust made him waver
(doubtingly question) concerning the promise of God, but he grew strong and was empowered by faith as he gave praise and glory to God, Fully satisfied and assured that God
was able and mighty to keep His word and to do what He had promised. (Romans 4:20, 21 AMP)

Abraham had committed his life to God that is he had consecrated his life in total surrender to God now he trusted Him with unwavering faith to hold His promise. Are we doing the same?
