When Jesus died on the cross, HIS testament went into effect. Laws that were not carried over - (mentioned in the New Testament) were dropped. It’s why we can eat pork and shellfish etc, and Jews (bound by the Old Testament) can’t. Lots of differences...
The law of Moses was abolished on the Cross. It was a shadow and ceremonial laws pointing to the coming Messiah but now that He has come, it has expired. That just leaves the Law of God. The Ten Commandments. The one the Bible calls holy, perfect and eternal. ut-oh. I see a problem. God wants us to worship on the day He has designated. The Sabbath. Who does God think He is anyways, our Creator?
If ye love Me, keep My Commandments" seems pretty definite to me. How about you? Are you squirming for a loophole?
