4:23-25 The history of Abraham, and of his justification, was recorded to teach men of after-ages; those especially to whom the gospel was then made known. It is plain, that we are not justified by the merit of our own works, but by faith in Jesus Christ and his righteousness; which is the truth urged in this and the foregoing chapter, as the great spring and foundation of all comfort. Christ did meritoriously work our justification and salvation by his death and passion, but the power and perfection thereof, with respect to us, depend on his resurrection. By his death he paid our debt, in his resurrection he received our acquittance, Isa 53:8. When he was discharged, we, in Him and together with Him, received the discharge from the guilt and punishment of all our sins. This last verse is an abridgement or summary of the whole gospel.
23-25. Now, &c.—Here is the application of this whole argument about Abraham: These things were not recorded as mere historical facts, but as illustrations for all time of God's method of justification by faith.
