⁶ “And the Lord your God will circumcise your heart and the hearts of your descendants [that is, He will remove the desire to sin from your heart], so that you will love the Lord your God with all your heart and all your soul, so that you may live [as a recipient of His blessing].

²⁸ For he is not a [real] Jew who is only one outwardly, nor is [true] circumcision something external and physical. ²⁹ But he is a Jew who is one inwardly; and [true] circumcision is circumcision of the heart, by the Spirit, not by [the fulfillment of] the letter [of the Law]. His praise is not from men, but from God.

¹¹ In Him you were also circumcised with a circumcision not made with hands, but by the [spiritual] circumcision of Christ in the stripping off of the body of the flesh [the sinful carnal nature], ¹² having been buried with Him in baptism and raised with Him [to a new life] through [your] faith in the working of God, [as displayed] when He raised Christ from the dead.
