A baby is born and filled with physical life and grows in every way throughout its life into maturity and knowledge. The new birth, a second birth, is a spiritual birth, but it too grows into spiritual maturity and knowledge or is overpowered by the flesh in an internal death struggle.
A born again Christian is a totally new thing being created... The Greek word for this "new creature" is ktisma.
This spiritual process of "making" Christians from a dual nature (spirit and flesh), into a single new spiritual creature, is a work in progress from the moment of the "new birth" unto the moment of death or rapture. That spiritual process is taking place in every Christian still in a body of flesh. The remaking and perfecting of the "new creature" shall continue right up to the resurrection and rapture of true believers.loved, now are we the sons of God, and it doth not yet appear what we : but know that, when he shall appear, we 1 John 3:2.
In the meantime, until that great day of resurrection, rapture and full, spiritual glorification, like unto Jesus, let the spirit of God purge out the old dead works and continue his work of grace making us a completely new creature in Christ.

"That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness." Eph.4:22-24.
"Lie not one to another, seeing that ye have put off the old man with his deeds; And have put on the new man, which is renewed in knowledge after the image of him that created him..." Col.3:9-10
"Knowing this, that our is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin." Rom.6:6
The Apostle Paul, who wrote that last verse about the "old man" and our "body of sin" continued and expanded upon the thought of the two fold nature of man and how they are at war with each other, in Romans 7 below. In this chapter, Paul uses himself and his life experience of his inner spiritual man battling the old fleshly man to grow in grace and serve God faithfully. This chapter tells the self-righteous they are sinners too. It tells the judgmental Christian that they are as guilty as those they judge. It tells the "sinless" person they are liars. It tells the humble, repentant Christian they are in the will of God. Here is the heart of Paul confessing in absolute honestly the truth about himself... and us.
