Ephesians 4:21-24 AMP

If in fact you have [really] heard Him and have been taught by Him, just as truth is in Jesus [revealed in His life and personified in Him], that, regarding your previous way of life, you put off your old self [completely discard your former nature], which is being corrupted through deceitful desires, and be continually renewed in the spirit of your mind [having a fresh, untarnished mental and spiritual attitude], and put on the new self [the regenerated and renewed nature], created in God’s image, [godlike] in the righteousness and holiness of the truth [living in a way that expresses to God your gratitude for your salvation].
