After receiving the divine life in regeneration, we experience a present, continuous salvation (1 Corinthians 15:2 and prior post) which is a much more salvation in Christ’s life (Romans 5:10). By this daily salvation, we grow unto New Jerusalem.
Colossians 2:19 describes our growth. This verse proclaims that “holding the Head, out from whom all the Body, being richly supplied and knit together by means of the joints and sinews, grows with the growth of God.” We grow with the growth of God! God is eternally complete; in Himself He does not grow. However, He grows in us. When we hold the Head, Christ, a bountiful supply flows out from Him into us resulting in the growth of God in us.
In 1 Corinthians 3:6 Paul says, “I planted, Apollos watered, but God caused the growth.” Paul and Apollos labored as God’s fellow workers (v. 9) yet only God Himself could give the growth because the growth is the increase of God in us. The essence of growth is not an increase in Bible knowledge nor improvement in behavior. (God’s growth in us will result in more insight into His word and will change our behavior. But, those changes could come from other factors, so they are not an assurance of growth.)
Life is God in Christ, who through the Spirit’s regeneration (John 3:6) lives in us; “Christ lives in me” (Galatians 2:20). Growth in life is the increase of life, which is the increase of God in Christ living in us. This is the life of New Jerusalem, the life which we enjoy now and will enjoy eternally with the river of life and the tree of life (Revelation 22:1-2).
