2 Corinthians 10:5

Casting down imaginations
Or "reasonings"; the carnal reasonings of the minds of natural men against God, his providences and purposes, against Christ, and the methods of salvation, and every truth of the Gospel; which are all disproved, silenced, and confounded, by the preaching of the word, which though reckoned the foolishness and weakness of God, appears to be wiser and stronger than men; and whereby the wisdom of the wise is destroyed, and the understanding of the prudent brought to nothing:

and every high thing that exalteth itself against the knowledge of
God;
every proud thought of the heart, every great swelling word of vanity, every big look, even all the lofty looks and haughtiness of men, with every airy flight, and high towering imagination, reasoning, and argument advanced against the Gospel of Christ; which is here meant by the knowledge of God, and so called, because it is the means of leading souls into the knowledge of God, even into a better knowledge of him than can be attained to, either by the light of nature, or law of Moses; to a knowledge of him, and acquaintance with him in Christ the Mediator, in whom the light of the knowledge of the glory of God is given; and with which knowledge of God eternal life is connected, yea, in this it consists; it is the beginning of it, and will issue in it.

And bringing into captivity every thought to the obedience of
Christ;
or "carrying captive the whole understanding"; that is, so illustrating it with divine light, that it clearly sees Christ to be the alone, able, willing, full, and suitable Saviour, and so becomes obedient to him, both as a Saviour and a King; such an enlightened soul looks to him alone for life and salvation, ventures on him, and relies upon him, and is desirous and willing to be saved by him in his own way; he receives and embraces all his truths and doctrines with faith and love, and obeys them from the heart, and cheerfully and willingly submits to all his commands and ordinances; for though he is taken by the grace of God, and all his strong holds, reasonings, and high thoughts are demolished by the power of God in the Gospel, and he himself is carried captive, yet not against, but with his will, to be a voluntary subject of Christ, and cheerfully to submit to the sceptre of his kingdom.
