Albert Barnes Commentary Romans 4:24

"but for our sake also, unto whom it shall be reckoned, who believe on him that raised Jesus our Lord from the dead," — Romans 4:24 (ASV)

But for us also. For our use (1 Corinthians 10:11), that we might have an example of the way in which people may be accepted by God. It is recorded for our encouragement and imitation, to show that we may in a similar manner be accepted and saved.

If we believe on him. Abraham showed his faith in God by believing just what God revealed to him. This was his faith, and it might be as strong and implicit as could be exercised under the fullest revelation. Faith, now, is belief in God just so far as he has revealed his will to us.

It is therefore the same in principle, though it may have reference to different objects. It is confidence in the same God, according to what we know of his will. Abraham showed his faith mainly in confiding in the promises of God respecting a numerous posterity. This was the leading truth made known to him, and this he believed.

The main or leading truths that God has made known to us are: that he has given his Son to die; that he has raised him up; and that through him he is ready to pardon. To put confidence in these truths is to believe now. Doing this, we believe in the same God that Abraham did; we show the same spirit and thus demonstrate that we are the friends of the same God and may be treated in the same manner. This is faith under the gospel , and shows that the faith of Abraham and of all true believers is substantially the same, being varied only by the difference of the truths made known.
