Kehillah in Corinth I 2:4

4 And my speech and my hachrazah (proclamation, kyrygma, preaching) to you of the Besuras HaGeulah of Hashem was not in persuasive words but in the demonstration of the Ruach Hakodesh and the gevurat Hashem (power of G-d—1:17),

Kehillah in Corinth I 2:4 Meaning and Commentary

1 Corinthians 2:4

And my speech, and my preaching
As he determined, so he acted. As the subject matter of his ministry was not any of the liberal arts and sciences, or the philosophy and dry morality of the Gentiles, but salvation by a crucified Christ; so his style, his diction, his language used in preaching,

was not with enticing words of man's wisdom;
with technical words, words of art, contrived by human wisdom to captivate the affections; and with bare probable arguments only, a show of reason to persuade the mind to an assent, when nothing solid and substantial is advanced, only a run of words artfully put together, without any strength of argument in them; a method used by the false teachers, and which the apostle here strikes at, and tacitly condemns:

but in demonstration of the Spirit, and of power;
partly by making use of solid proofs out of the writings of the Old Testament, indited by the Spirit of God, and which amounted to a demonstration of the truths he delivered; and partly by signs, and wonders, and miracles, and gifts of the Holy Ghost, those extraordinary instances of divine power, which greatly confirmed the doctrines he preached: and besides all these, the Spirit of God wonderfully assisted him in his work, both as to words and matter; directing him, what to say, and in what form, in words, not which human wisdom taught, but which the Holy Ghost taught; and accompanying his ministry with his power, to the conversion, comfort, edification, and salvation of many.

Kehillah in Corinth I 2:4 In-Context

2 For I made the decision not to have da’as of anything among you except Moshiach and nivlato al haEtz (his body –gufa, kerper—on the Tree Boim (Yiddish for tree), DEVARIM 21:23).

3 And I came to you (Ac 18:1) in weakness (1:25,27) and in yir’at Shomayim and in fear and in much trembling I was with you,

4 And my speech and my hachrazah (proclamation, kyrygma, preaching) to you of the Besuras HaGeulah of Hashem was not in persuasive words but in the demonstration of the Ruach Hakodesh and the gevurat Hashem (power of G-d—1:17),

5 That the [orthodox Jewish] emunah (faith) of you may not be in the [Olam Hazeh] "chochmah" of Bnei Adam, but in the gevurat Hashem [1:17].

6 But we do speak chochmah (wisdom) to the man who is mevugar (mature, grown up), to those with mature ruchaniyut (spirituality in Rebbe, Melech HaMoshiach), yet, it is a chochmah (wisdom) not of the Olam Hazeh, neither of the rulers of the Olam Hazeh (Ro 13:3), the ones being brought to naught (1:28). [TEHILLIM 146:4]
