2 Corinthians 5:17
Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come.
In the New Testament, the Christian life is often described as “putting off” and “putting on.” If we are to live as new creations in Jesus Christ, then we need to understand exactly how to put off the old self and put on the new self which has been recreated in Christ Jesus. Romans 6:11-14 tells us exactly how to do this.
