For in Christ Jesus neither circumcision nor uncircumcision avails anything, but a new creation.
Galatians 6:15 (NKJV)
In Jesus we have been made a new creation. Our walk with the Lord has nothing to do with circumcision, uncircumcision, or any other requirement of the old Mosaic law, but much rather is it about consistently remembering who we have been made to be in Him. The more we remember to live out of who Jesus has made us to be, the more will the fruits of our new life be righteousness, love, peace, joy and true fulfillment.
