1 Corinthians 1:18

"But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned."

"For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek."

"And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved."

"But if our gospel be hid, it is hid to them that are lost:"

"For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe."

"For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness."

"For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake."

"For I determined not to know any thing among you, save Jesus Christ, and him crucified."
