The wisdom of this world is not the same as Gods wisdom, for God says the wisdom of the world is foolishness to Him. Those things which the world deems as most important is of no value in the eyes of God. That which is spiritual is opposite of the language the world speaks, therefore the world will not understand. It is by the holy spirit Gods wisdom is made easy to understand. ( 1 Corinthians 2:10-16) 10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. 11 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. 12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 13 Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. 14 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. 15 But he that is spiritual judgeth all things, yet he himself is judged of no man. 16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.
There is a definite separation of the children of God and the children of the world. Jesus spoke about this with His Father as He says they are His children given Him out of the world by His Father (John 17:5-10) 5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was. 6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word. 7 Now they have known that all things whatsoever thou hast given me are of thee. 8 For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me. 9 I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine. 10 And all mine are thine, and thine are mine; and I am glorified in them.
Those of the world will understand others of the world because they speak of the world, but for those who are born of the spirit they speak Christ crucified and are of God (1 John 4:1-6) 1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. 2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: 3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. 4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. 5 They are of the world: therefore speak they of the world, and the world heareth them. 6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
