XII. Again, in the Epistle to the Corinthians he says: “For my speech and my preaching was not in the enticing words of man’s wisdom, but in demonstration of the Spirit and of power; that your faith should not stand in the wisdom of men, but in the power of God.” 325 And again he says: “As it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love Him. But God hath revealed them unto us by His Spirit: for the Spirit searcheth all things, yea, the deep things of God. For what man knoweth the things of a man, save the spirit of man which is in him? Even so the things of God knoweth no man, but the Spirit of God.” 326 And again he says: “But the natural man receiveth not the things of the Spirit of God.” 327 325     1 Cor. ii. 4, 5 . 326     1 Cor. ii. 9–11 . 327     1 Cor. ii. 14 .
