Christ explains how to receive everlasting life..To be born again. The flesh birth of course is impossible. We must be reborn in Spirit and have the Spirit manifest in ourselves...
KJV
John6:5-12 Jesus answered and said unto him, Verily, verily I say unto thee, Except a man be born again he cannot see the kingdom of God. (6) Nicodemus saith unto him. How can a man be born when he is old? can he enter the second time into his mother's womb, and be born? (5) Jesus answered, Verily, verily, I say unto thee, Except a man be born of water, and of the Spirit, he cannot enter into the kingdom of God. (6) That which is born of the Spirit is spirit. (7) Marvel not that I said unto thee, Ye must be born again. (8) The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit. (9) Nicodemus answered and said unto him, How can these things be? (10) Jesus answered and said unto him, Art thou a master of Isreal, and knowest not these things? (11) Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. (12) If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things.Litteraly we must be born in the Spirit of God to enter heaven.
He explains in laymen's terms what everlasting life is like. How it is like never going thirsty again.
KJV
John 4:7-14 There cometh a woman of Samaria to draw water: Jesus saith unto her, Give me to drink (8) (For his disciples were gone away unto the city to buy meat.) (9) Then saith the woman of Samaria unto him, How is it that thou, being a Jew askest drink of me, which am a woman of Samaria? for the Jews have no dealings with the Samaritans. (10) Jesus answered and said unto her, If thou knewst the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water. (11) The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep: from whence then hast thou that living water? (12) Art thou greater than our father Jacob,which gave us the well, and drank thereof himself, and his children, and his cattle? (13) Jesus answered and said unto her, Whosoever drinketh of this water shall thrist again: (14) But whosoever drinketh of the water that I shall give himshall be in him a well of water springing up into everlasting life.
Then Christ tells her to call her husband and come to Him...Really He is reffering to God..Ya know the story of the bridegroom who has prepared for His bride and such..That is how the kingdom is described to us...She says she has no husband and asks Christ how to get that water that is like everlasting life. She then goes on to say how her people have worshipped in physical places..
KJV John 4:15-20 The woman saith unto him, Sir, give me this water, that I thirst not, neither come hither to draw. (16) Jesus saith unto her, Go, call thy husband, and come hither. (17) The woman answered and said, I have no husband, Jesus said unto her, Thou hast well said, I have no husband: (18) For thou hast had five husbands; and he whom thou now hast is not thy husband: in that saidst thou truly. (19) The woman saith unto him, Sir I percieve that thou art a prophet. (20) Our fathers worshipped in this mountian; and ye say, that in Jerusalem is the place where men ought worship.
Next Christ goes on to explain how the day will come when God will be worshipped not in the physical but in Spirit, and she is told by Christ that He will teach her and show her the way...
KJV John 4:21-26 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, not yet at Jerusalem, worship the Father. (22) *Ye worship ye know not what:* we know what we worship: for salvation is of the Jews. (23) But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and truth: for the Father seeketh such to worship him. (24) God is a Spirit: and they that worship him must worship him in spirit and in truth. (25) The woman saith unto him, I know that Messias cometh, which is called Christ: when he is come, he will tell us all things. (26) Jesus saith unto her, I that speak unto thee am he.**Something they obviously cannot see..Something not physical or fleshy..
Afterward when the disciples return they make no quarrel about this woman comming to Christ. They do not question Y she is there. The woman then takes her faith and leaves her old waterpot (that always needed to be refilled, but since finding Christ she had no need b/c she had the living water so that she might never thirst again..i.e..everlasting life.) She then goes to tell others of the good news and send them to Christ. (She bids them that they pay Him a visit...He knew everything about me how can he not be the Christ?)
KJV John 4:27-29 And upon this came his diciples, and marvelled that he talked with the woman: yet no man said, What seekest thou? or, Why talkest thou with her? (28) The woman then left her waterpot, and went her way into the city, and saith to the men, (29) Come, see a man, which told me all things that ever I did: is not this the Christ?
In the following verses Christ again speaks of needing the Spirit and not the physical things..
KJV John 4:30-32 Then they went out of the city, and came unto him. (31) In the mean while his disciples prayed him, saying, Master, eat. (32) But he said unto them, I have meat to eat that ye know not of.
Is God limited to a Spirit only? Well heck no...Christ had a fleshy body. God can do whatever He wants. I think the valid point is what God wants of us..He desires us to worship Him in spirit..Christ Himself tells us that God is a Spirit and so desires to be worshipped that way. He says we cannot see Him in the physical sense, but it matters not. We are to be reborn in spirit and follow after Christ and heed His teaching. In another sense is Christ with me? Yes He is always with me even though I cannot see Him.
