God's (Own) Life
occurs at regeneration?
You get a new spirit as well as quickened old one. "A new spirit I will put in you" - "That which is born of the Spirit is spirit" (Ezek. 36.26; John 3.6). His uncreated life is given to man's spirit, so it is made alive (quickens). The new life (or new spirit) belongs to God (2 Peter 1.4) and is unable to sin (1 John 3.9). Our spirit, though quickened, may yet be defiled (2 Cor. 7.1), needing to be sanctified (cleansed) - 1 Thess. 5.23.
God's life (Holy Spirit) entering our spirit quickens it out of a coma - "alienated from the life of God" (Eph. 4.18), it is made alive again. I am finding "uncreated life" to mean "eternal life" and the "life of God", but it is not God's Own Life (Holy Spirit or God's life).
When eternal life comes into man's spirit, it quickens the old spirit. As the Holy Spirit enters man's spirit, the new spirit allows the Holy Spirit an abode. The Holy Spirit needs that new spirit, otherwise He can not enter so He puts in man a new spirit, just as He enters or a split second before, like rolling out the red carpet.
God's life equals eternal life equals, a higher life or spirit life which is zoe. "This is eternal life," prayed Jesus to His Father, "that they know thee the only true God, and Jesus Christ whom though sent" (John 17.3). Eternal life is future blessings for believers, a spiritual ability to know God - without it you can not know God nor Jesus; intuitive knowledge of the Lord comes solely upon receiving God's life/nature, and a regenerated spirit has all the works of God before him.
Conclusion: we must not concern ourselves with the distinction amongst these terms:
1) life of God
2) God's own life
3) uncreated life
4) eternal life
5) God's nature
6) God's life
7) His Spirit
8) Holy Spirit
9) spirit life
11) new spirit
12) new life
13) higher life
Why do we not concern ourselves with the distinction of these terms?
Christians do not legalize the Word. We do not concern ourselves with separating these terms because it is impossible for the Holy Spirit to exist in our spirit without us having His life eternal; therefore, they are coincident. You can't have one without the other in reality. We are not God, but we have His same life of eternal life as His Spirit resides therein. There ought not to be a distinction because there is not a distinction in Rev. 22.1,3,4 being left with one face of God shown within the new city which still holds the Father's authority and the Son's submission, yet having only one face, and no mention of the Spirit. Because there is no specific mention of the Spirit, and though this is the 3rd Person of the Godhead, it is the same life we live with one distinction - we are not God. The promise of the Holy Spirit indwelling follows very closely the promise of having a new spirit. The Spirit is just preparing the groundwork of His Own indwelling by convincing sinners of sin and leading them to believe in the Lord, and then giving them a new spirit (new life).
"A new heart I will give you and a new spirit I will put within you . . . and I will put my Spirit within you" (Ezek. 36.26-27). This shows that a new spirit enters with the renewal of the deadened spirit by the incoming of life [God's life]. First, the new spirit is given, then the Spirit enters. The latter is the indwelling Holy Spirit.
At new birth believers receive a new spirit and the Holy Spirit in their renewed spirits. We live out that new life (new spirit) in the Holy Spirit indwelling. God's life on one hand means it is the new life we now live, while on the other hand, God's life is His Own Life of the Holy Spirit therein. The dweller and the dwelling must share the same characteristic. The Holy Spirit dwells where he builds. Unless there is an element within man unlike the flesh, the Holy Spirit finds Himself unable to dwell in the man. When one has God's life they have not only eternal life but God's indwelling Holy Spirit also since it is not possible to have one without the other. They are the same life. God's life, His Holy Spirit, has eternal life and for this, they are inseparable.
How do I know I have been regenerated, and how can you know you are regenerated? We know because our inner man has been quickened and the Holy Spirit dwells within. Our spirit is a regenerated, renewed one, and He who dwells in, yet is distinct from, this new spirit is the Holy Spirit. And the two of them bear witness together.
