Many Christians live as though the Law is for us now, but our relationship with the law was settled in Acts 15:

We have heard, that some of our number which went out from us, have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment. -Acts 15:24
It amazes me how many people submit to rules that trouble and subvert the soul and bring one under an endless weight of duty that Christ actually liberated us from. Many Christians want to peek in your pants and see if you are circumcised. They want you to follow their laws that they have adopted to determine who is in and who is out. Laws help them feel superior and OK with God. Laws are safe, predictable and measurable. But laws are like rabbits they multiply endlessly until they dominate everything.
Think about us Americans...we love laws. We have rules for everything. Where you can pee, how fast you drive, seatbelts, helmets, building permits, outdoor licenses, food and drink laws, noise laws, parking rules, laws for property, taxes, voting, business, education, walking your dog, what you can do with your own house..on and on it goes and they just keep growing! Soon we will have laws for breathing!
The same madness goes on in the church. Each group has their own signs of circumcision and particular laws that define them. Thankfully Jesus came to give us LIFE not laws and there is a huge difference between the two. One leads to freedom and the other to bondage.
Like Paul, I am thankful to be able to proclaim that I have died to the law. Choose life not law and beware those who would try to bewitch you into following Jesus by the works of the law. Remember it was for freedom that Christ set you free.
