Thematic Bible: Why the world cannot receive nor know the spirit of God

Jesus says to Him, Am I so long time with you, and hast thou not known me, Philip? The one having seen me hath seen the Father: how do you say, Show us the Father? Dost thou not believe, that I am in the Father, and the Father is in me? The words which I speak unto you I speak not of myself: but the Father who abideth in me doeth His own works. Believe me that I am in the Father, and the Father in me; or if not, believe for the sake of the works themselves. read more.
Truly, truly, I say unto you, He that believeth on me, shall also do the works which I am doing; and shall do greater works than these: because I go to the Father: and whatsoever you may ask in my name, I will do it, in order that the rather may be glorified in the Son. If you may ask anything of me in my name, I will do it. If you love me, keep my commandments. And I will ask the Father, and He will give you another Comforter, that He may be with you always, the Spirit of truth: which the world is not able to receive, because it does not see Him, nor know Him: you know Him: because He abideth with you, and shall be in you. I will not leave you orphans: I am coming to you. Vet a little while, and the world sees me no more; but you see me: because I live, you shall live also.

But the intellectual man receives not the things of the Spirit of God; for they are foolishness unto him; and he is not able to know them, because they are spiritually discerned. But the spiritual man discerns all things, and is himself discerned by no one. For who knows the mind of the Lord, who shall give him counsel? But we have the mind of Christ.
