And the Lord your God will circumcise your heart and the heart of your descendants, to love the Lord your God with all your heart and with all your soul, that you may live. —Deuteronomy 30:6
Circumcision is the surgical removal of the male foreskin, usually performed shortly after birth. It is a symbol of God “cutting away” from our hearts the “covering” of fleshly attitudes that prevent us from loving and serving Him.
Often we trust in mere instruction and discipline to effect this change in our children. In this verse, God is promising to do it supernaturally. Convincing a child through logic and reason is nowhere near as powerful as when that child has an encounter with God that transforms him or her from within. Praise God, the Most High pledges to do that very thing (Rom. 2:28–29).
Lord, I claim for my child a circumcised heart, that You will “cut away” the worldliness, the carnality and the sensuality that could otherwise corrupt him/her. I acknowledge that this is a promised divine deliverance, a supernatural act of God, and not something I can force by mere religious instruction. I trust You, Lord, to work this awesome, internal transformation in ___________ and give him/her a circumcised heart. In the name of Jesus, amen (let it be so)!
