Hebrews 4:13

Neither. Literally, “and.”

Creature. Gr. ktisis, any “thing created,” that is, constituted an entity in and of itself (see on Rom. 8:19), here, doubtless, the man of v. 12 whose thoughts and motives have been judged by God’s “word.” Men are able to judge only on the basis of a man’s words and acts, but God’s “word” goes back of man’s words and deeds to the place where they originate and judges a man on the basis of what goes on in the mind. “Man looketh on the outward appearance, but the Lord looketh on the heart” (1 Sam. 16:7).

Not manifest in his sight. Or, “hidden before him.” No man can hide his thoughts and motives from God. Try as he may, no man can run away from God (cf. Ps. 139:7-10).

All things. That is, the thoughts and motives of each “creature,” or man.

Naked and opened. Or, “uncovered and exposed.” Nothing can be concealed from God.

Him with whom we have to do. Literally, “with whom, for us, the reckoning,” that is, before whom we must give an account of ourselves. The realization that he must account for his words and deeds before so discerning a Judge may well sober the most callous of sinners; certainly it should make the professed Christian give the most diligent consideration to his thoughts and motives. Compare Rom. 14:10-12; 2 Cor. 5:10.
