As I said, we will have to accept we disagree on this issue.

If you do intend to try and earn your salvation or gain God's blessings through the law like the Jews do (the New Testament tells us it's in doing kindness to others that we please God not by bodily mutilations or animal sacrifices), then like Paul says, you will have to follow the law to the letter. As only Christ has ever been able to do this, hence why we are set free from the law now he fulfilled it in our place (hence why we trust him as saviour), you're setting yourself up for one heck of a challenge. Good luck.
