I Corinthians 2:4

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, Mat 7:29; Act 6:10; Heb 4:12; compare also Rom 15:19). The same simple power accompanies divine truth now, producing certain persuasion and conversion, when the Spirit demonstrates by it.

The apostle proceeds with his argument in this chapter, and, I. Reminds the Corinthians of the plain manner wherein he delivered the gospel to them (Co1 2:1-5). But yet, II. Shows them that he had communicated to them a treasure of the truest and highest wisdom, such as exceeded all the attainments of learned men, such as could never have entered into the heart of man if it had not been revealed, nor can be received and improved to salvation but by the light and influence of that Spirit who revealed it (Co1 2:6 to the end).
