Romans 4:19-21

New King James Version

¹⁹ And not being weak in faith, ^(A)he did not consider his own body, already dead (since he was about a hundred years old), ^(B)and the deadness of Sarah’s womb. ²⁰ He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God, ²¹ and being fully convinced that what He had promised ^(C)He was also able to perform.
