1 Corinthians 1:21

For seeing that in the wisdom of God the world through its wisdom knew not God, it was God's good pleasure through the foolishness of the preaching to save them that believe. [Here Paul quotes Isaiah 24:14 to show that God had foretold how he would make foolish and useless all kinds of worldly wisdom, Grecian or Jewish, by making the gospel the only means of salvation, and how he had carried out the prophecy; for in his wisdom, or plan of operation, he had frustrated the efforts of wise men to find or know him by their coldblooded, philosophical research, or speculative reasoning (Acts 17:23), and showed that it was his good pleasure to reveal himself and his salvation through this (to them) foolish preaching, and save them who believe the preaching. Where, then, asked the apostle in triumph, are these men of worldly wisdom, be they scribes or philosophical dialecticians? What have they done in comparison with that gospel which reveals their efforts as foolish and useless? What place, then, has a wise Paul or a disputing Apollos in the church, which, having the gospel, has this superior, saving wisdom of God? and why should the Corinthians leave the leadership of God in Christ and return to fools?]
