1 Corinthians 15:
45 So also it is written, “The first man, Adam, became a living soul”; the last Adam became a life-giving Spirit.
6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
12 But as many as received Him, to them He gave the authority to become children of God, to those who believe into His name,
13 Who were begotten not of blood, nor of the will of the flesh, nor of the will of man, but of God.
11 And if the Spirit of the One who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who indwells you.
1 Corinthians 6:
17 But he who is joined to the Lord is one spirit.
Christ Becoming the Life-Giving Spirit to Enter into His Believers
After passing through the first four major processes of incarnation, human living, crucifixion, and resurrection, Christ in His resurrection became a life-giving Spirit (1 Cor. 15:45b). In His resurrection Christ became such a life-giving Spirit in order that He might enter into His believers (John 20:22). Today, anywhere on this earth, wherever and whenever a person calls on the name of the Lord Jesus, believes in Him, and receives Him as his Savior, this life-giving Spirit immediately enters into him. This means that Christ as the life-giving Spirit enters into His believers. Have you believed in the Lord Jesus? Have you called on His name and received Him? If so, you should realize that He has entered into your innermost being. He is the Almighty God, the Almighty Creator, and He became a perfect man. As such a One He accomplished everything. He died for us, He was buried, and He was resurrected. In His resurrection He was transfigured into the life-giving Spirit. Now this life-giving Spirit is not restricted by anything. He is not limited by time or by space. He is everywhere, He is present, and He is now. He is present with you just like the air. Wherever you go there is air. Whenever you open your mouth, air gets into you. This is why Romans 10:8 tells us that Christ as the living Word is near you, even in your mouth and in your heart.
Christ as the Life-Giving Spirit Regenerating the Believers in Their Spirit
As the life-giving Spirit, Christ has regenerated the believers in their spirit (John 3:5-6). Doctrinally, it is difficult to explain how Christ, after entering into us, regenerates us in our spirit. However, in experience it is simple. When a sinner repents, confesses his sins, believes in the Lord Jesus, and calls on His name, at that very moment Christ as the life-giving Spirit enters into his spirit to enliven his dead spirit, that is, to regenerate him in his spirit. Immediately such a person becomes alive, happy, and joyful. He cannot explain what has happened to him, but he is rejoicing. He may continue to repent of his sins for the remainder of the day. A great change has taken place in his life. This sinner has been saved. He has been regenerated, and he is now a Christian.
The believers’ regenerated spirit and Christ who is the life-giving Spirit are joined to be one spirit (1 Cor. 6:17). This is wonderful. We, the believers in Christ, all have a regenerated spirit. Our spirit was dead, but through believing in Christ it has been made alive (Eph. 2:1). Now we all have within us our own spirit which has been regenerated and made alive. At the same time Christ as the life-giving Spirit is within our spirit. These two spirits are joined to be one spirit. This is a most mysterious and wonderful thing. That our spirit is joined to Christ, the life-giving Spirit, as one spirit is a most crucial and vital matter. This is the ultimate consummation of the organic union which we have with Christ. No union could be more intimate than this union.
