20 Who verily was foreordained He again by a comparison amplifies the grace of God, with which he had peculiarly favored the men of that age. For it was not a common or a small favor that God deferred the manifestation of Christ to that time, when yet he had ordained him in his eternal council for the salvation of the world. At the same time, however, he reminds us, that it was not a new or a sudden thing as to God that Christ appeared as a Savior; and this is what ought especially to be known. For, in addition to this, that novelty is always suspicious, what would be the stability of our faith, if we believed that a remedy for mankind had suddenly occurred at length to God after some thousands of years? In short, we cannot confidently recumb on Christ, except we are convinced that eternal salvation is in him, and always has been in him. Besides, Peter addressed the Jews, who had heard that he had already been long ago promised; and though they understood nothing true or clear or certain respecting his power and office, yet there remained among them a persuasion, that a Redeemer had been promised by God to the fathers.
It may yet be asked, As Adam did not fall before the creation of the world, how was it that Christ had been appointed the Redeemer? for a remedy is posterior to the disease. My reply is, that this is to be referred to God’s foreknowledge; for doubtless God, before he created man, foresaw that he would not stand long in his integrity. Hence he ordained, according to his wonderful wisdom and goodness, that Christ should be the Redeemer, to deliver the lost race of man from ruin. For herein shines forth more fully the unspeakable goodness of God, that he anticipated our disease by the remedy of his grace, and provided a restoration to life before the first man had fallen into death. If the reader wishes for more on this subject, he may find it in my Institutes.
But was manifest, or manifested. Included in these words, as I think, is not only the personal appearance of Christ, but also the proclamation of the Gospel. For, by the coming of Christ, God executed what he had decreed; and what he had obscurely indicated to the fathers is now clearly and plainly made known to us by the Gospel. He says that this was done in these last times, meaning the same as when Paul says,
“In the fullness of time,” (Galatians 4:4;)
for it was the mature season and the full time which God in his counsel had appointed.
For you He does not exclude the fathers, to whom the promise had not been useless; but as God has favored us more than them, he intimates that the greater the amplitude of grace towards us, the more reverence and ardor and care are required of us.
