When you came to Christ, you were “circumcised,” but not by a physical procedure. Christ performed a spiritual circumcision—the cutting away of your sinful nature.
According to this verse, those who believe (in heart and mind) on what Christ did on the cross for us, and truly loves Him so much that you are always in UNION with Him, have their ‘sinful nature’ already cut off by Christ!
You do not have a sinful nature anymore! You can now be victorious over any stubborn, recurring, “any-type” sin that may be in your life right now!
Christ has changed our sinful nature into a believing nature. A nature that desires to follow Christ more than desiring to follow unChrist-like desires. We have been made more than a conqueror. God has made sure that He provided ALL THINGS so that we would be able to live a joyful, peaceful, victorious Christian life!
