Nothing to be added or subtracted from God’s Word? (Deut. 4:1-8)
“You shall not add to the word which I command you, nor take from it.”

“There are many circumstances of life about which the Scriptures are silent and God has allowed for man's creative faculties to flourish. But in areas where God has clearly stated His will for men in the form of law, nothing is to be added or subtracted. These areas of law are, to be sure, broader than the activities of worship, and yet worship is certainly included within the scope of the command. Where God has clearly spoken, as He has regarding worship, man is not free to add or subtract from his Word…

The distinction between life as a whole and worship lies behind the distinction between the six days of Labor and the Sabbath day. Hence anti -Sabbatarians use the same superficial argument-‘we are to live every day to the glory of God’ Now, of course we are to live every day to the glory of God, but six days out of seven we are to live to the glory of God in the home, in the kitchen, at the office, and at the factory, but on the Sabbath day we are to live to the glory of God by engaging in the specific ordinances of His worship. There is a distinction between glorifying God in our daily living and glorifying God in our conscious approach to Him in worship. The denial of that distinction is destructive of the Sabbath and it is destructive of any biblical attempt to know how to worship God.” (Comin 48, 49).
