Jesus warned us in the book of John that any attempt to dilute or obscure that truth that Jesus lives to become us, comes from the pit of hell. The specific scripture states that all spirits subject to the authority of Christ assure people that He Himself has come in our flesh.
This is quite a different slant to the usual use of the word flesh in the new testament. Paul uses flesh to mean carnality and Watchman Nee is correct to speak of carnal christianity in this vein. In John the Spirit of Christ means us to interpret the text as the Spirit of Christ incarnated in our being. This is certainly the meaning Athanasius gives it, as do all theologies that harmonise with the teaching of the apostles. It’s the same meaning as Paul’s ‘In Him we live, move and have our being.’ Christ really does become our life.
We are talking here of the incarnation which is the new covenant reality of Christ our life. Here the Spirit of Jesus manifests as the sons and daughters of God: All who believe Christ’s gospel and have entered their union with Him. This union is unlike the old covenant. In Adam and Moses people were influenced by the Holy Spirit. None lived in the Spirit until Jesus came among us and none could until His death when the new covenant began with the ripping of the temple curtain. ‘It was finished!’ What was finished? The separation that Adam began was finished and the union with God initiated and accomplished by God began at the at-one-ment of the cross.
“Knowing the first covenant is not like the second will bring this clear distinction between the two covenants: The old way depended upon the people to dedicate and commit their lives towards fulfilling the commands. The new way depends upon the One who already fulfilled the commands and has committed his life to us … Throughout the writings of the New Testament, we see a constant comparison of old covenant law to new covenant grace. “For the Law was given through Moses; grace and truth were realized through Jesus Christ” (John 1:17 NASB). Notice the contrast! On the one hand there is the law that came through Moses; on the other hand, grace and truth realized through Jesus Christ. (1)
The lie that led to The Fall was the insinuation that there was some lack. Adam and Eve were not ‘as gods’ because they were not really sons and daughters of God. Father had pulled some kind of a swiftie on them and therefore could not be trusted. But there already were as gods because they were sons and daughters of God. This lie is the same deceit Satan uses today. Through the cross, the atonement and the incarnation Jesus has made us one with God. We are no longer sons notionally – unless we persist in the separation of the law. We are sons in spirit and in truth because the sonship of Jesus is our sonship and His relationship with each member of the trinity is our relationship with the trinity.
Grace and truth undo the lie and annul the separation. Grace and truth is the enterprise of love enacted by the trinity on our behalf. The stunningly gracious act of God is the cross where God was in Christ reconciling the world to Himself. The amazingly clever plan is the manifestation of the life of the trinity in you and I on an ongoing basis as our incarnated life in the Spirit. The lie of the Enemy is that the law is still operative and it is Jesus who assists in our keeping of the law. It’s a mongrel gospel. The pure Gospel is that Christ Himself is our life. He graces us with His life as ours. We live in the fellowship of their life as ours. We are joined by the Christ to the Family of God as the sons and daughters of God.
