2:1-5 Christ, in his person, and offices, and sufferings, is the sum and substance of the gospel, and ought to be the great subject of a gospel minister's preaching, but not so as to leave out other parts of God's revealed truth and will. Paul preached the whole counsel of God. Few know the fear and trembling of faithful ministers, from a deep sense of their own weakness They know how insufficient they are, and are fearful for themselves. When nothing but Christ crucified is plainly preached, the success must be entirely from Divine power accompanying the word, and thus men are brought to believe, to the salvation of their souls.

4. my speech—in private.

preaching—in public [Bengel]. Alford explains it, My discourse on doctrines, and my preaching or announcement of facts.

enticing—rather, "persuasive."

man's wisdom—man's is omitted in the oldest authorities. Still "wisdom" does refer to "man's" wisdom.

in demonstration of … Spirit, &c.—Persuasion is man's means of moving his fellow man. God's means is demonstration, leaving no doubt, and inspiring implicit faith, by the powerful working of the Spirit (then exhibited both outwardly by miracles, and inwardly by working on the heart, now in the latter and the more important way only, Mt 7:29; Ac 6:10; Heb 4:12; compare also Ro 15:19). The same simple power accompanies divine truth now, producing certain persuasion and conversion, when the Spirit demonstrates by it.
