2 Corinthians 10:5

5.And bring into captivity I am of opinion, that, having previously spoken more particularly of the conflict of spiritual armor, along with the hinderances that rise up in opposition to the gospel of Christ, he now, on the other hand, speaks of the ordinary preparation, by which men must be brought into subjection to him. For so long as we rest in our own judgment, and are wise in our own estimation, we are far from having made any approach to the doctrine of Christ. Hence we must set out with this, that

he who is wise must become a fool, (1 Corinthians 3:18,)

that is, we must give up our own understanding, and renounce the wisdom of the flesh, and thus we must present our minds to Christ empty that he may fill them. Now the form of expression must be observed, when he says, that he brings every thought into captivity, for it is as though he had said, that the liberty of the human mind must be restrained and bridled, that it may not be wise, apart from the doctrine of Christ; and farther, that its audacity cannot be restrained by any other means, than by its being carried away, as it were, captive. Now it is by the guidance of the Spirit, that it is brought to allow itself to be placed under control, and remain in a voluntary captivity.
