(23-25) Application of the foregoing. The history of Abraham is a type of the dispensation of grace; his faith, the imputation of righteousness to him, and his reward, each severally a type of the same things in the Christian. Even in details the resemblance holds. Abraham put faith in a God "who quickeneth the dead," and in like manner the Christian must put faith in God as the Author of a scheme of salvation attested by the resurrection of Christ. The death of Christ was the ground of that scheme, the resurrection of Christ its proof, without which it would not have been brought home to man.

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.Now it was not written for his sake alone,.... This was not left on the sacred records, Genesis 15:6,

that it was imputed to him; purely on his account, merely for his sake, as an encomium of his faith, and an honourable testimony to it, and for the encouragement of it; though this was doing him a very great honour, and was one design of it.
