Well, I'm now feeling well out of my depth! So I'll leave it to you guys who actually know what you are talking about ;)You can fool some of the people... (Winston Churchill)I wonder if we dig into this verse a bit where it will lead us and how it might connect with John 3. This is a ‘thinking aloud’ document! There are 3 things mentioned, water, blood, Spirit. The last part of the section says that ‘the three’ all agree 'into one'; that is to say they all combine their witness in one purpose. (the words witness, record, testimony are all translations of the same Greek word - martureō - to bear witness) This verse is going one better than two witnesses which would normally be required for evidence and the witness of all three, water, blood, spirit is unanimous.The 'witness' is to the person of Jesus Christ. How are we to understand this? As the topic opens we have the 'three'; water, blood, Spirit. I notice that although the 'three' are not always in the same order...ie. in verse 6 we have (w+b)+ Swhereas is verse 8 we have S + (w+b)...water and blood are always in the same relationship to each other. (w+b) seems to be an identifiable unit. It is literally 'the water and the blood'.Verse 6 speaks of Christ 'having come'. This is an Aorist participle and has the sense of a completed event. Now what can 'having come' refer to, particularly in that such a 'coming' was 'by' (dia-through) (w+b)? verse 20 of this chapter says;And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life. (1Jo 5:20 KJV)That ‘the life’ was manifested in Christ is one of John’s themes;And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water. (Joh 1:31 KJV)Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? (Joh 14:22 KJV)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. (Joh 17:6 KJV)(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) (1Jo 1:2 KJV)And ye know that he was manifested to take away our sins; and in him is no sin. (1Jo 3:5 KJV)He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. (1Jo 3:8 KJV)In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. (1Jo 4:9 KJV)It seems that this is what has ‘come’ the manifestation of a life which had witness born to it by water, blood and Spirit.Other than in 1John 1:7 'blood' is only used in these two verses in this letter. 'Blood' on its own like this is usually short-hand for the work done on the cross. So can we add that value into our equation? that Christ 'came' through (water and 'the redeeming work of the cross')John Baptist's specific role was prepare the setting in which Christ could be made manifest to Israel.And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water. (Joh 1:31 KJV)and it was at His baptism that this took place. So I think we have a value for 'water' here too; baptism. This was the setting in which the Father first 'witnessed' to the identity of the Son. If this is the case 'the water and the blood' are the borders of His earthly ministry; in terms of geography, Jordan and Calvary. How is 'the blood' an event in which the Father bore witness to the Son? One of the first things we hear about ‘blood’ in the Scripture is that it speaks; And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground. (Gen 4:10 KJV)And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. (Heb 12:24 KJV) So Christ’s ‘blood’ speaks and ‘bears witness’. The physical cross, that took place in time and space, is the outward working of an inward and invisible spiritual reality where the blood (the redeeming death of His Son) was brought into heaven’s Holy of Holies. This is the great theme of Hebrews 9, but the whole of Hebrews is a proof of the identity of the Son of God. ((KJV) Heb1:2; Heb1:5; Heb1:8; Heb2:6; Heb3:6; Heb4:14; Heb5:5; Heb5:8; Heb6:6; Heb7:3; Heb7:28; Heb10:29; Heb11:17; Heb11:24; Heb12:5; Heb12:6;)The Spirit is certainly a witness to His identity and person. who was marked out the Son of God in power, according to the Spirit of holiness, by the resurrection from the dead; (Rom 1:4 MKJV) The word translated ‘declared’ is more accurately translated in the Jay Green Modern KJV.So we have a three-fold witness to the identity of the life of the Son of God manifested in Jesus Christ; The Father, who spoke at His ‘water’ baptism. The Son who presented His own blood in His sinless, redeeming, death, and the Spirit who, by raising Him from the death, testified to His identity as the Son of God. The three witnesses are unanimous in their testimony. The three witnesses also mark three key points. The Son of God is not only He who was declared so as He came out of the ‘water’, but who accomplished redemption as the Son, and who is raised by the Spirit, as the Son. Is this the ‘full identity’ of the life that was manifest? If it had only been ‘by water’ it would have been incomplete in its manifestation. The death of Christ was the greatest manifestation of the life of the Son of God.The Christ to whom ‘the three’ bear witness, is the one whose identity is set forth in all three events, and the three events themselves describe who He is; the Son of God whose life perfectly pleased the Father, the Son of God whose perfect life was given in a redeeming sacrifice which achieved atonement and reconciliation, the Son of God who lives in the resurrection power of an endless life. The Son of God to whom ‘the three’ bear unanimous testimony is He whose perfect life pleased the Father, whose perfect life paid the ransom, and whose perfect life is continually manifested in the person and work of the Holy Spirit.This may seem to have run on from the original question, but I think it lends some support to the view that ‘born of water’ is a link with ‘water baptism’ rather than ritual cleansing. OK guys n gals, “destruction test” it!
