Some wonder: does it really matter which day we worship on? Let’s allow the Bible to answer:
God instituted the seventh-day Sabbath (Saturday) at creation, “Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made. … And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made” (Genesis 2:1-3). The seventh day Sabbath identifies the true God and His claim of ultimate sovereignty as the Creator. No other day can fit God’s purpose.
God blessed the seventh day because He created the world in six days and rested on the seventh. The Sabbath was the birthday and the memorial of the world. The Sabbath can’t be changed because it points backward to a specific act. In the same manner, a person’s birthday can’t be changed because it is a memorial of his birth.
Most of the Ten Commandments begin with the same words: “Thou shalt not,” but the fourth commandment starts with the word, “Remember” (Exodus 20:8-11). Why is this one different? Because God was commanding His children to call something to memory which already existed but had been forgotten.
It does matter that we should worship on the seventh day because it was God’s commanded. What was the original sin of Adam and Eve? Eating from THE forbidden TREE. What was so evil about eating from that tree? Adam and Eve’s act was an act of disobedience to God’s command. That one sin resulted in the destruction of the human race and planet Earth. And it resulted in the death of God’s only Son on the cross.
God is very serious about His commands. Jesus said, “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled” (Matthew 5:17-18). And He added, “It is easier for heaven and earth to pass, than one tittle of the law to fail” (Luke 16:17).
