What do the Titles given by the Holy Spirit Mean?

But the seventh day is the sabbath of the LORD thy God: 

Exodus 20:10

"Throughout the New Testament the seventh day of the week is called the Sabbath, and the first day of the week is known only by that

designation. 

Q: What does that signify? 

A: It means that those are the titles that the Holy Spirit designs that those days shall bear throughout all time. 

The Bible is the word of God, and when God gives a name to a thing, it means that the thing is just what He names it. So the seventh day is the Sabbath, and so it will always be, no matter what men may do."
