God said to keep the commandments. Yes I know how and that is to keep His commandments. Do you kill, do you steel, do you commit Adultery. I am sure you do not. That is keeping Gods commandments and yes they are still binding on Christians. But where people fail is the Fourth commandment. They throw it out, that being "remember the Sabbath day" the seventh day,and keep it Holy.
Most individuals trample all over it and say that it is for the Jews only.
I guess God made a mistake and give another day in it place? I do not thing so.
