64. But there are some of you who do not believe. He again imputes blame to them, because, being destitute of the Spirit, they wickedly corrupt and debase his doctrine, and thus turn it to their ruin. For otherwise they might have objected: “You boast, indeed, that what you speak is quickening, but we experience nothing of that nature.” He therefore says, that by themselves it is prevented; for unbelief, as it is always proud, will never understand any thing in the words of Christ which it despises and disdains. Wherefore, if we wish to profit at all under this Teacher, let us bring minds well disposed to listen to him; for if the entrance to his doctrine be not opened up by humility and reverence, our understandings are harder than stones, and will not receive any part of sound doctrine. And therefore, when in the present day we see so few people in the world profiting by the Gospel, we ought to remember that this arises from the depravity of men. For how many will you find who deny themselves, and truly submit to Christ? As to his saying only that there were some who did not believe, though almost all of them were liable to this charge, his reason for doing so appears to have been that, if there were any who were not yet beyond the possibility of cure, they might not cast down their minds in despair.
For Jesus knew from the beginning. The Evangelist added this, that none might think that Christ formed an opinion at random about his hearers. Many professed to belong to his flock, but a sudden apostacy exposed their hypocrisy. But the Evangelist says that their treachery, even while it was unknown to others, was well known to Christ. And this is stated, not so much on his account, as that we may learn not to form a judgment except on subjects which we have thoroughly investigated; for as to their being known to Christ from the beginning, this was peculiar to his Divinity. It is otherwise with us; for since we do not know the hearts, we ought to delay forming a judgment, until impiety be manifested by outward signs, and thus the tree be known by its fruits, (Matthew 7:16.)
