The Predestination of the Saints/Gift of Perseverance

Therefore in Him who is our Head let there appear to be the very fountain of grace, whence, according to the measure of every man, He diffuses Himself through all His members. It is by that grace that every man from the beginning of his faith becomes a Christian, by which grace that one man from His beginning became Christ. Of the same Spirit also the former is born again of which the latter was born. By the same Spirit is effected in us the remission of sins, by which Spirit it was effected that He should have no sin.

God certainly foreknew that He would do these things. This, therefore, is that same predestination of the saints which most especially shone forth in the Saint of saints; and who is there of those who rightly understand the declarations of the truth that can deny this predestination? For we have learned that the Lord of glory Himself was predestinated in so far as the man was made the Son of God. The teacher of the Gentiles exclaims, in the beginning of his epistles, “Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God (which He had promised afore by His prophets in the Holy Scriptures) concerning His Son, which was made of the seed of David according to the flesh, who was predestinated the Son of God in power, according to the Spirit of sanctification by the resurrection of the dead.” Therefore Jesus was predestinated, so that He who was to be the Son of David according to the flesh should yet be in power the Son of God, according to the Spirit of sanctification, because He was born of the Holy Spirit and of the Virgin Mary.

This is that ineffably accomplished sole taking up of man by God the Word, so that He might truly and properly be called at the same time the Son of God and the Son of man—Son of man on account of the man taken up, and the Son of God on account of the God only-begotten who took Him up, so that a Trinity and not a Quaternity might be believed in. Such a transporting of human nature was predestinated, so great, so lofty, and so sublime that there was no exalting it more highly—just as on our behalf that divinity had no possibility of more humbly putting itself off, than by the assumption of man's nature with the weakness of the flesh, even to the death of the cross.

As, therefore, that one man was predestinated to be our Head, so we being many are predestinated to be His members. Here let human merits which have perished through Adam keep silence, and let that grace of God reign which reigns through Jesus Christ our Lord, the only Son of God, the one Lord. Let whoever can find in our Head the merits which preceded that peculiar generation, seek in us His members for those merits which preceded our manifold regeneration. For that generation was not recompensed to Christ, but given; that He should be born, namely, of the Spirit and the Virgin, separate from all entanglement of sin.

Thus also our being born again of water and the Spirit is not recompensed to us for any merit, but freely given; and if faith has brought us to the laver of regeneration, we ought not therefore to suppose that we have first given anything, so that the regeneration of salvation should be recompensed to us again; because He made us to believe in Christ, who made for us a Christ on whom we believe. He makes in men the beginning and the completion of the faith in Jesus who made the man Jesus the beginner and finisher of faith; for thus, as you know, He is called in the epistle which is addressed to the Hebrews.
