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 Without becoming weak in his faith, Abraham accepted the fact that he was past the time when he could have children. At that time he was about 100 years old. He also realized that Sarah was too old to have children.

20 But he kept believing in God's promise. He became strong in his faith. He gave glory to God.

21 He was absolutely sure that God had the power to do what he had promised.

22 That's why "God accepted Abraham because he believed. So his faith made him right with God."

23 The words "God accepted Abraham's faith" were written not only for Abraham.
