For Jesus knew from the beginning— Our Lord insinuates, that he knew who would believe in him among the vast multitude of his auditors; and more particularly, that he knew who would continue his disciples among those who had professed themselves such, even from their first attending him; and that even among his apostles he knew who was to betray him; and that, consequently, in choosing him he was guilty of no indiscretion, as, in continuing him among the apostles, he shewed that he did nothing in his greatest privacies which was culpable. It is plain from this verse, that God foresees future contingencies:
But his foreknowledge causes not the fault, Which had no less prov'd certain, unforeknown.
See on John 6:71.
