Romans 4:20 in the King James Version
He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
Context
19 Without being weakened in faith, he didn’t consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah’s womb.
20 Yet, looking to the promise of God, he didn’t waver through unbelief, but grew strong through faith, giving glory to God,
21 and being fully assured that what he had promised, he was also able to perform.
