Acts 3:17

17, 18. At this point in the discourse there is a marked change in Peter's tone and manner, which we can attribute to nothing else than some visible indication of the intense pain produced by what he had already said. He had made a most terrific onslaught upon them, and exposed their criminality in unsparing terms; but now, induced by some perceptible change in their countenances, he softens his style, and extenuates their fault. (17) "And now, brethren, I know that you did it in ignorance, as did also your rulers. (18) But those things which God had before announced through the mouth of all his prophets, that Christ should suffer, he hath thus fulfilled." That they acted in ignorance of the real character of Jesus was an extenuation of their crime, but it did not render them innocent; for the preceding remarks were intended to convict them of crime, and in his preceding discourse he charged that with wicked hands they had crucified and slain him. Peter assumes, what none of them could honestly deny, that it was by wicked motives they were impelled to the fatal deed.

In connection, with this assertion of their criminality, he states another fact hard to be reconciled with it in the philosophy of man, that, in the commission of this crime, God was fulfilling what he had declared through his prophets should be done. Once before, in speaking of this same event, Peter had brought these two apparently conflicting facts, the sovereignty of God, and the free agency of man, into juxtaposition, when he said, "Him, being delivered by the determined purpose and foreknowledge of God, you have taken, and with wicked hands have crucified and slain." That God had predetermined the death of Jesus can not be denied without contradicting both the prophets and the apostles; and that they acted wickedly in doing what God had determined should be done, Peter affirms, and three thousand of them on Pentecost, with many more on this occasion, admitted it. If any man can frame a theory by which to philosophically reconcile these two facts, we will assent to it, if we can understand it; but unless both facts, unaltered have a place in the theory, we must reject it. We reject every man who denies either of the facts; but while he admits them both, we will not dispute with him about the theory upon which he attempts to reconcile them. This much, fidelity to the word of God on the one hand, and brotherly kindness on the other hand, demand of us. In the mean time, it is better to follow Peter's example. He lays the two facts side by side, appealing to the prophets for the proof of one, and to the consciences of men for the proof of the other, and there he leaves them, seeming not to realize that he had involved himself in the slightest difficulty. It is folly to attempt to climb where we are certain of a fall.
