The deistic theory that man can by the light of nature discover his duty to God, is disproved by the fact that man has never discovered it without revelation.

Even the Jew missed this knowledge, in so far as he followed after mere carnal world wisdom. it pleased God--Paul refers to Jesus' words (Luk 10:21). by the foolishness of preaching--by that preaching which the world (unbelieving Jews and Gentiles alike) deem foolishness. save them that believe-- (Rom 1:16).

In this chapter we have, I. The preface or introduction to the whole epistle (Co1 1:1-9). II. One principal occasion of writing it hinted, namely, their divisions and the origin of them (Co1 1:10-13). III. An account of Paul's ministry among them, which was principally preaching the gospel (Co1 1:14-17). IV. The manner wherein he preached the gospel, and the different success of it, with an account how admirably it was fitted to bring glory to God and beat down the pride and vanity of men (Co1 1:17 to the end).

1:21 Human wisdom alone does not bring people to the true knowledge of God; that comes only through the message of the cross, which the world considers foolish, but which saves those who believe (cp. Matt 11:25).
