The Christian life is fundamentally a changed life. If you claim to believe in Christ, but are living just as you did before you believed in Him, you need to examine whether you truly believe in Him. Becoming a Christian requires turning from your sin to God (in other words, repentance). But repentance is not a one-time event. It defines the lifestyle of a believer. God changes us radically at the moment of salvation by imparting new life to us, but this is followed by a lifetime of changing into the image of Jesus Christ (2 Cor. 3:18).

 

Other Scriptures referenced include Ephesians 4:15, 17-32 and Proverbs 27:17.
