Immediately the sinner believes in the Lord Jesus he is born anew. God grants him His uncreated life that the sinner’s spirit may be made alive. The regeneration of a sinner occurs in his spirit. God’s work begins without exception within the man, from the center to the circumference. How unlike Satan’s pattern of work! He operates from the outer to the inner. God aims first to renew man’s darkened spirit by imparting life to it, because it is this spirit which God originally designed to receive His life and to commune with Him. God’s intent after that is to work out from the spirit to permeate man’s soul and body.
This regeneration gives man a new spirit as well as quickens his old one. “A new spirit I will put within you”—“That which is born of the Spirit is spirit” (Ezek. 36.26; John 3.6). The “spirit” in these passages has God’s life in view, for it is not what we originally possessed; it is accorded us by God at our regeneration. This new life or spirit belongs to God (2 Peter 1.4) and “cannot sin” (1 John 3.9) ; but our spirit, though quickened, may yet be defiled (2 Cor. 7.1) and in need of being sanctified (1 Thess. 5.23).
When God’s life (which can equally be called His Spirit) enters our human spirit, the latter is quickened out of its coma. What was “alienated from the life of God” (Eph. 4.18) is now made alive again. Hence “although your bodies are dead because of sin, your spirits are alive because of righteousness” (Rom. 8.10). What we are given in Adam is a spirit made dead; what we receive in Christ at regeneration is both the dead spirit quickened and the new spirit of God’s life: the latter, something Adam never had.
In the Bible God’s life is often labeled “eternal life.” “Life here is zoe in Greek, denoting the higher life or spirit life. This is what every Christian receives at his regeneration. What is the function of that life? “This is eternal life,” prayed Jesus to His Father, “that they know thee the only true God, and Jesus Christ whom thou hast sent” (John 17.3). Eternal life means more than mere future blessing to be enjoyed by believers; it is equally a kind of spiritual ability. Without it no one can know God nor the Lord Jesus. Such intuitive knowledge of the Lord comes solely upon receiving God’s life. With the germ of God’s nature within him, an individual can ultimately grow into a spiritual man.
God’s aim in a regenerated man is for that man by his spirit to rid himself of everything belonging to the old creation, because within his regenerated spirit lie all the works of God towards him.
