When one becomes a “New Creation” those old things mean nothing to you anymore. First, it is an inward change of heart and of mind when Christ comes into one’s life, but then second, it is the obvious outward change in behavior and lifestyle that brings all glorify and honor to the Lord Jesus Christ.
Paul said that circumcision or uncircumcision meant nothing to him. Friends, there are a lot of people who want you to spend time and energy on stuff that doesn’t matter, but don’t take the bait, spend time with the Lord Jesus and sharing His love, His cross and resurrection and the love of God which provides for us our eternal home in heaven. You may be tempted to go overboard with some idea in the scripture or the Blood Moons or the Revelation or other books of prophecies of the end time but be careful and watch out what takes up your time. Notice, Paul says that those who follow his recommendation will receive peace and mercy from God Himself. Paul wanted none of the converts in the province of Galatia to turn back into the slavery of the law again. A prisoner who is freed from his cell does not go back and lock himself up. That is not reasonable. So it is not reasonable for the believer to return to the law and give up his freedom in Christ.
