The Sabbath was God's day of rest. He had created our reality and then he stopped to let our history play out. That is how He rested because God does not need to rest. We are living in God's 7th day (the Sabbath) and we should keep our every days holy by loving God, worshiping Him, thanking him, and obeying Him by loving all people as we love ourselves on a daily basis.
We should always love God and Love our neighbour, we should always worship Him.
The sabbath is a wonderful gift.
But it also is a command. It is for our good.
Because of tradition and worldly pressures people don't want to change.
That is why most didn't accept Christ when He came the first time.
Everything that God does perfectly the devil needs to distort.
God gave the 7th day and it was made holy. Gen And God blessed the seventh day, and sanctified it:..
The devil changed it to Sunday, and said it's not something we need to remember anymore.
The Bible is clear that it is the 7th day and we are not told to stop keeping it.
A question for the Catholic church....
Q. Have you any other way of proving that the Church has power to institute festivals of precept?
A. Had she not such power, she could not have done that in which all modern religionists agree with her; —she could not have substituted the observance of Sunday the first day of the week, for the observance of Saturday the seventh day, a change for which there is no Scriptural authority.
