See how faith worked with his works, and by works was faith made perfect?
All Commentaries on James 2:22 Go To James 2
Bede
AD 735
Abraham had such a vibrant faith in God that he was ready to do whatever God wanted him to. This is why his faith was reckoned to him as righteousness, and it was in order that we might know the full meaning of this that God ordered Abraham to sacrifice his son. It was by his perfect accomplishment of God's command that the faith which he had in his heart was shown to be perfect.
