Ephesians 4:21 Meaning

19Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.

20But ye have not so learned Christ;

21If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:

22That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;

23And be renewed in the spirit of your mind;
