G.W. North emphasizes that the life of Jesus, characterized by the law of the Spirit of life, frees us from the law of sin and death. He explains that while we are not under the Mosaic law, we are still governed by the law of righteousness and life, which allows us to live free from sin. North highlights the importance of walking in the Spirit to experience the fullness of Christ's life, as this is the only way to embody the moral intelligence and personality that God intends for us. He asserts that the Holy Spirit enables us to live as children of God, witnessing our sonship and leading us in the life of Christ. Ultimately, the sermon calls believers to embrace their identity in Christ through the Spirit.

We therefore see that the unique life of Jesus of Bethlehem and Nazareth and Calvary was produced entirely by the law of the Spirit of life. This is the life which God means us to understand when we read the phrase 'the Spirit of life in Christ Jesus'. This life is not subject to the law of sin and death simply because it is the law of righteousness and life, and all the time we live by it we shall live free from sin as God intends us to. Other laws must operate too, all combining to this end. We must observe John's statement for instance — 'if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin'. We do not ordinarily think of that operation as law, but it is. When Paul says, 'ye are not under law but under grace', he does not mean that under grace all law is suspended or nullified; he means these two things: (1) we are not now under the Mosaic legal system of blood sacrifices for sin or thank offerings etc., (2) we are not now under the law of sin and death. We are here being instructed into the law of being and personality; in all moral intelligences these co-exist. In fact, without moral intelligence, personality cannot be. There can be physical that is to say animal existence, but no one ever thinks of speaking of an animal as a person; it may have an intelligence of a sort, but it is not moral, it does not act morally but instinctively according to its nature. A higher will and intelligence may train it to respond to a certain name and to do certain things, but it will never be thought of as a being, a person. It will remain a creature, an animal; it has being, therefore existence, but without personality. On the other hand, man, in common with angels and God, has moral intelligence; all three have both being and personality. In God's being there is no sin, therefore there is no death in Him because sin is the cause of death. But beyond, far beyond this negative aspect of His being, God is positively righteous. Being always morally right and good He is eternally alive — He is life itself. His nature is love and His personality is grace — that is to say that in His attitude towards us God is always gracious. Apparently this graciousness was the quality of nature and personality which came through most strongly to people of Jesus' acquaintance; 'the grace of our Lord Jesus Christ' certainly made terrific and unforgettable impact on Paul. Now exactly the same life that was in Christ is in the Holy Spirit, as it is in the Father also; although they share the same life, they embody and express it in three different ways as three distinct yet related persons. We must express this life also, and for this reason must walk in the Spirit and after the Spirit. God has ordained it that way for us, but He did not do so for the sake of it, He did so because there is no other way. It was quite impossible on earth for men to walk in the life of Jesus of Nazareth the human being. They could walk after Him — that is, follow Him — with Him or away from Him, but not in Him. Men could not walk in what He was in the flesh. That was unique, but in the Spirit it is now possible (and O what grace this is) to walk in what Christ is in spirit. To this end the Holy Spirit is now in charge of all things to do with Christ. We must be in the Spirit and after the Spirit and be led by the Spirit or we cannot have and shall not know the life of Christ. We may have and enjoy some of His benefits, but that is not good enough for God's sons. Beyond all these He wants us to have the privileges of sonship, and enjoy all the benefits of a son and heir of God. Therefore the Spirit is made unto us the Spirit of adoption or sonship, and this He accomplishes by coming into us and witnessing with our spirits that we are the children of God.
