Ephesians 4:21-25

when you heard about Christ and were taught in him in accordance with the truth that is in Jesus. You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness. Therefore each of you must put off falsehood and speak truthfully to your neighbor, for we are all members of one body.
