⁵³ For this perishable [part of us] must put on the imperishable [nature], and this mortal [part of us that is capable of dying] must put on immortality [which is freedom from death].

²² 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, ²³ and be continually renewed in the spirit of your mind [having a fresh, untarnished mental and spiritual attitude], ²⁴ 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].

¹⁷ Therefore if anyone is in Christ [that is, grafted in, joined to Him by faith in Him as Savior], he is a new creature [reborn and renewed by the Holy Spirit]; the old things [the previous moral and spiritual condition] have passed away. Behold, new things have come [because spiritual awakening brings a new life].

Paul Reveals His Heart

7 Therefore, since we have these [great and wonderful] promises, beloved, let us cleanse ourselves from everything that contaminates body and spirit, completing holiness [living a consecrated life—a life set apart for God’s purpose] in the fear of God.

⁸ Come close to God [with a contrite heart] and He will come close to you. Wash your hands, you sinners; and purify your [unfaithful] hearts, you double-minded [people].

¹⁵ For neither is circumcision anything [of any importance], nor uncircumcision, but [only] a new creation [which is the result of a new birth—a spiritual transformation—a new nature in Christ Jesus].

⁷ but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].
