2 Corinthians 4:13

Moreover, our Mediator, when revealed to us, wished the sacrament of our regeneration to be manifest. But for the just men of old it was something hidden, although they also were to be saved by the same faith which was to be revealed in its own time. For we do not dare to prefer the faithful of our own time to the friends of God by whom those prophecies were to be made, since God so announced himself as the God of Abraham, the God of Isaac, the God of Jacob, as to give himself that name forever. If the belief is correct that circumcision served instead of baptism in the saints of old, what shall be said of those who pleased God before this was commanded, except that they pleased him by faith, because, as it is written in Hebrews: "Without faith it is impossible to please God"? "But having the same spirit of faith," says the apostle, "as it is written: I believed, for which cause I have spoken, we also believe, for which reason we also speak." He would not have said "the same" unless this very spirit of faith was also theirs. For, just as they, when this same mystery was hidden, believed in the incarnation of Christ which was to come, so we also believe that it has come.

Those just men also were saved by their salutary faith in him as man and God. They, before he came in the flesh, believed that he was to come in the flesh. Our faith is the same as theirs, since they believed that this would be, while we believe that it has come to pass. Hence, the apostle Paul says: "But having the same spirit of faith, as it is written: I believed for which reason I have spoken: we also believe for which reason we also speak." If, then, those who foretold that Christ would come in the flesh had the same faith as those who have recorded his coming, these religious mysteries could vary according to the diversity of times yet all refer most harmoniously to the unity of the same faith.

"But having the same spirit of faith, according to that which is written, I believed, and therefore did I speak; we also believe, and therefore also we speak; that He which raised up the Lord Jesus, shall raise up us also by Jesus." He has reminded us of a Psalm which abounds in heavenly wisdom, and is especially fitted to encourage in dangers. For this saying that just man uttered when he was in great dangers, and from which there was no other possibility of recovery than by the aid of God. Since then kindred circumstances are most effective in comforting, therefore he says, "having the same Spirit;" that is, 'by the same succor by which he was saved, we also are saved; by the Spirit through which he spake, we also speak.' Whence he shows, that between the New and Old Covenants great harmony exists, and that the same Spirit wrought in either; and that not we alone are in dangers, but all those of old were so too; and that we must find a remedy through faith and hope, and not seek at once to be released from what is laid upon us. For having showed by arguments the resurrection and the life, and that the danger was not a mark of helplessness or destitution; he thenceforward brings in faith also, and to it commits the whole. But still of this also, he furnishes a proof, the resurrection, namely, of Christ, saying, "we also believe, and therefore also we speak." What do we believe? tell me.

Above he mentioned trials and death, then said that Jesus delivered us from them as well, and gave the reason that He delivered us precisely in order to assure us of His resurrection. Now he affirms that this must be grounded in faith, and not …

Then the Apostle shows how he acquired this hope of certainty. In regard to this he does two things. First, he states the cause of the certainty; secondly, he concludes to the certainty itself (v. 14). Now the cause of this certainty is the Spirit …
