We should be continually changing, transforming, morphing into the person and people God has created us to be. The Apostle Paul understood this:
1 Corinthians 3:3 (Amplified Bible)
3For you are still [unspiritual, having the nature] of the flesh [under the control of ordinary impulses]…Are you not behaving yourselves after a human standard and like mere unchanged men?
Paul is saying that there must be evidence of change in our lives. He is saying that if there is not change, something is wrong.
