Christ, as “the Spirit of Life,” is the Fullness of the Godhead Now In us
Col. 2:9-10 For in him (in Christ) dwelleth all the fulness of the Godhead bodily. 10And ye are complete in him, which is the head of all principality and power:
The Spirit “in us" is for our personal realization of righteousness, peace and joy. Rom 14:17 the kingdom (realm) of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost. In fact, all the attributes and benefits of God’s life are now… “in Christ,” and they come to us … by the indwelling “Spirit of life in Christ Jesus.”
The “Spirit of Christ” in the believer is “the truth” or reality of Christ Himself for us to realize personally as our “comforter.”
John 14:16-20 And I (Jesus) will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth (the Truth – Christ is the “reality”); whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. 18I will not leave you comfortless: I will come to you. 19Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also. 20At that day ye shall know that I am in my Father, and ye in me, and I in you. < Ask yourself, who is in the believer?
· NOTE: In v16 & 17 the Lord refers to the Holy Spirit as “he,” but in verse 18, the pronoun changes from “he” to the “I” who was speaking to them at that time – The “I” was and is “Jesus.”
§ By changing the “he” who was with them (in verses 16-17) to “I” in v18 the Lord was saying the “he” is the “I” who is to return as the Spirit to indwell them.
§ The Holy Spirit that Jesus spoke of in v16-17…is He Himself, but then as “the Spirit of Life” (Rom 8:2a)
We see Jesus as the “living water” here in John 4:14 But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life. Also below, in John 7:38-39, we see the “the Spirit” is the “water of life.” Both Jesus and the Spirit are “the water of life” because they are One and the same.
We need to note that in the KJV, the word “given” (v39 below) is italicized because it was incorrectly added by the translators. It is not in the oldest original Greek manuscripts. You see, it’s not that “the Spirit” was “not yet given,” rather it’s that Christ had not yet glorified since he had not yet completed the transformation from the man “Jesus of Nazareth” into being “the Spirit of life.”
John 7:38-39 (KJV) He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. 39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
Here above the Holy Spirit is seen as the “water of the life” of the resurrected Christ who then was still “not yet,” meaning “not yet in existence” because Jesus had not yet completed the process by which He would become available as “the Spirit of life” to indwell the believers.
Obviously then, Jesus and the Holy Spirit are one in the same, seen here as…the “water of life.” The “Spirit is life” and it is “Christ who is our life” (
Col3:4a), so “the Spirit” and “Christ” are One as the real life indwelling the believer’s spirit.
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. Romans 8:2 …the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. Col. 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
“The Spirit” then is Spirit of the One Godhead, God the Father, and Christ, as the new life to indwell believers. Note here the various terms to describe who it is that is “in you.”
Romans 8:8-10 So then they that are in the flesh cannot please God.  But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God (the Father) dwell in you. Now if any man have not the Spirit of Christ, he is none of his.  And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
“The Spirit of life in Christ Jesus” is the culmination of Jesus of Nazareth’s human experience on earth, now as “the life-giving spirit.”
1 Cor. 15:45 …the last Adam was made a quickening (life-giving) spirit.
John 6:63 It is the spirit that quickeneth (gives life); the flesh profiteth nothing.
1 John 4:13 Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit.
