The Bible Sabbath

Why the Seventh Day? Why did God bless the seventh day as a day of worship? Because He had just created the world in six days. It was a memorial to the birth of the world, a reason to remember that mighty act. So could the Sabbath memorial be changed? No. Because it points backward to an accomplished fact. For instance, July 4 is Independence Day in the United States. Can it be changed? No. Because the Declaration of Independence was signed on July 4, 1776. Your birthday cannot be changed either. It is a memorial of your birth, which happened on a set day. History would have to run through again to change your birthday, to change Independence Day, or to change the Sabbath day. We can call another day Independence Day, and we can call another day the Sabbath, but that does not make it so.
