God lives fully in Christ. And you are fully grown because you belong to Christ, who is over every power and authority. Christ has also taken away your selfish desires, just as circumcision removes flesh from the body.
As a follower of Jesus Christ you will find that He circumcises your heart and takes away your selfish desires!
Circumcision was a sign that a Jewish man belonged to God. The sign was a reminder primarily for the man himself. He was marked by God at a private place that would rule his life, if God did not rule it.
Circumcision of the heart is the mark of God today. Circumcision of the heart is not just for men, but for all followers of Jesus. Jesus marks your heart by cutting off part of your heart and leaving a scar that always reminds you that you belong to Him. Like circumcision of the flesh the sign is not for everyone to see, but it is to constantly remind you that you belong to Jesus!
Without Jesus your own heart will rule your life. You will do whatever your heart desires and you will follow your own dreams and live your life only for your own pleasure. But if you have given your heart to Jesus, then He will be the Ruler of your life and you will do whatever He desires, even if what He desires is opposed to what your own heart would like!
So if you want to be a follower of Jesus, then let Him put His mark on your heart! It is a mark that will last forever!
"Lord Jesus, take my heart and cut off everything in my heart that opposes You. Leave me Lord with a heart that only beats to do Your will! And may I do that will Today! May You be praised forever. Amen."
