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.

But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.

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

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

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

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

Then certain philosophers of the Epicureans, and of the Stoicks, encountered him. And some said, What will this babbler say? other some, He seemeth to be a setter forth of strange gods: because he preached unto them Jesus, and the resurrection. babbler: or, base fellow

And when they heard of the resurrection of the dead, some mocked: and others said, We will hear thee again of this matter.

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.

By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. keep...: or, hold fast what: Gr. by what speech
