I Corinthians 14:25

And thus--omitted in the oldest manuscripts and versions. secrets of his heart made manifest--He sees his own inner character opened out by the sword of the Spirit (Heb 4:12; Jam 1:23), the word of God, in the hand of him who prophesieth. Compare the same effect produced on Nebuchadnezzar (Dan 2:30 and end of Dan 2:47). No argument is stronger for the truth of religion than its manifestation of men to themselves in their true character. Hence hearers even now often think the preacher must have aimed his sermon particularly at them. and so--convicted at last, judged, and manifested to himself. Compare the effect on the woman of Samaria produced by Jesus' unfolding of her character to herself (Joh 4:19, Joh 4:29). and report--to his friends at home, as the woman of Samaria did. Rather, as the Greek is, "He will worship God, announcing," that is, openly avowing then and there, "that God is in you of a truth," and by implication that the God who is in you is of a truth the God.

In this chapter the apostle directs them about the use of their spiritual gifts, preferring those that are best and fitted to do the greatest good. I. He begins with advising them of all spiritual gifts to prefer prophesying, and shows that this is much better than speaking with tongues (Co1 14:1-5). II. He goes on to show them how unprofitable the speaking of foreign languages is, and useless to the church; it is like piping in one tone, like sounding a trumpet without any certain note, like talking gibberish; whereas gifts should be used for the good of the church (Co1 14:6-14). III. He advises that worship should be celebrated so that the most ignorant might understand, and join in prayer and praise, and presses the advice by his own example (Co1 14:15-20). IV. He informs them that tongues were a sign for unbelievers rather than those that believe; and represents the advantage of prophecy above speaking with tongues, from the different suggestions they would give to the mind of an unbeliever coming into their assemblies (Co1 14:21-25). V. He blames them for the disorder and confusion they had brought into the assembly, by their vanity and ostentation of their gifts; and directs them in using the gifts both of tongues and prophecy (Co1 14:26-33). VI. He forbids women speaking in the church; and closes this subject by requiring them to perform every thing in the public worship with order and decency (Co1 14:34 to the end).

14:25 “God is truly here among you.” Paul is alluding to Isa 45:14.
