Romans 4:20-22

Amplified Bible, Classic Edition

²⁰ 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,

²¹ Fully satisfied and assured that God was able and mighty to keep His word and to do what He had promised.

²² That is why his faith was credited to him as righteousness (right standing with God).
