Romans 4:21 Meaning and Commentary

Romans 4:21

And being fully persuaded
He had not only faith, a strong faith, but full assurance of faith:

that what he [God] had promised;
though it was so long ago, and there were so many difficulties in the way;

he was able,
being the Lord God Almighty,

to perform;
so his faith rested upon the power of God, with whom nothing is impossible.

Romans 4:21 In-Context

19 His trust did not waver when he considered his own body - which was as good as dead, since he was about a hundred years old - or when he considered that Sarah's womb was dead too.
20 He did not by lack of trust decide against God's promises. On the contrary, by trust he was given power as he gave glory to God,
21 for he was fully convinced that what God had promised he could also accomplish.
22 This is why it was credited to his account as righteousness.
23 But the words, "it was credited to his account . . . ," were not written for him only.
