Romans 4:19-20

4:19 Without being weak in faith, he considered his own body as dead (because he was about one hundred years old) and the deadness of Sarah’s womb. 4:20 He did not waver in unbelief about the promise of God but was strengthened in faith, giving glory to God.

Romans 5:2

5:2 through whom we have also obtained access by faith into this grace in which we stand, and we rejoice in the hope of God’s glory.
