To add to my previous post--I don't see any reason not to honor the sabbath and keep it holy-but never to become legalistic about it. I am still trying to sort the thing out as I just begun to study it very recently.
It is one of the 10 Commandments written by the very finger of God in STONE. Jesus said, " If you love me, you will keep my commandments." I have always attended church on Sunday. I have been looking and looking for a new church--during this time I have been studying denominations and was disturbed by all the false teaching I discovered in ALL of them. One day, I was looking at the Commandments and began to wonder why we keep all the Commandments with exception of the Sabbath--I looked up bible verses and could find nothing in the New Testament where the Sabbath was done away with. There are a number of the verses in Acts where both Jews and Gentiles gathered to hear Paul speak on the Sabbath--again they met every day, but why do meet on Sunday--that is as an assembly--only because Constantine changed Sunday to the Sabbath--it's like the inverted cross of Satanists--the Sabbath says God's work is finished. Sunday is the opposite of that. There is more than just about a day--God sanctified it--therefore it is into perpetuity..
Note that when it says let no one judge you on xyz...or on a sabbath day--this is different than THE Sabbath--these were special days, like Holidays. Again, this is not about legalism--as I said, I am still trying to come to a better understanding of this myself.
