A good marriage as opposed to a mere relationship involves the union of a man and a woman in body soul and spirit. Its source is the relationship in the trinity. Our relationship with God is seen in the archetype of marriage.
Just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me
Jesus did not leave us with a new way of living in the old knowledge of good and evil – even with His help. Neither did He leave us a Jesus empowered religious discipline. He did leave us a life in in Him. This is a life in His life that is not a religious life at all. This mode of existence is what Paul called, CHRIST OUR LIFE.
They are three because they are one..
It is our interwoveness with God and God's interwoveness with us that is life to the full.
This new and living way is called the NEW COVENANT and the vicarious humanity of Jesus. It means more than Jesus in you. It means Jesus AS YOU. This is meaning of the incarnation. It is what life in the Spirit can never be the gifts added to old covenant motions. It is the gifts springing from the fact that we and our Father are one. Stephen Crosby writes,
It's the new covenant!
“In the new covenant, God is not dependent on humanity living correctly to receive His life and blessing. He secures His own interests in humanity by putting His Spirit in us as a free gift of His sovereign and unmerited goodwill. The indwelling Spirit is both the life gift and the power source. Out of the life given, behavior follows. Therefore, in the new covenant our obedience is not our gift to God, which merits His blessing. Our obedience is His gift to us, the fruit of the life we have freely received manifested in our actions.” (1)
But this is not all. We get more than a program and agenda of good deeds as opposed to bad actions. We get life itself. And not religious life. We get spirit and life that is the flow of the life of God in and through us.
