Answer: The natural mind knows nothing of the things of God. They are foolishness to it. The preaching of the cross is foolishness to them that perish, but unto us who are saved, it is the power of God. It pleased God by the foolishness of preaching (the gospel) to save them that believe. It is the power of God, but a stumbling block to the Jews. To the Greeks, foolishness, but unto the called ones, both Jews and Greeks, it was Christ, the power of God and the wisdom of God. So the gospel is the weakness and the foolishness of God, but it is stronger and wiser than men.
The natural mind talked about it as being weak and foolish, and God’s answer is the 25th verse. God has chosen the foolish things of the world, to confound the wise; and God hath chosen the weak things of the world, to confound the mighty. And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to naught things that are: “That no flesh should glory in His presence.”
Everything is ours in Christ, the despised One. God teaches us to glory only in Him.
“He that glorieth, let him glory in the Lord.”
