And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters. Revelation 14:6-7.
By the first angel, men are called upon to “fear God, and give glory to Him” and to worship Him as the Creator of the heavens and the earth. In order to do this, they must obey His law. Says the wise man: “Fear God, and keep His commandments: for this is the whole duty of man.” Ecclesiastes 12:13. Without obedience to His commandments no worship can be pleasing to God. “This is the love of God, that we keep His commandments.” “He that turneth away his ear from hearing the law, even his prayer shall be abomination.” 1 John 5:3; Proverbs 28:9. GC 436.1
The duty to worship God is based upon the fact that He is the Creator and that to Him all other beings owe their existence. And wherever, in the Bible, His claim to reverence and worship, above the gods of the heathen, is presented, there is cited the evidence of His creative power. “All the gods of the nations are idols: but the Lord made the heavens.” Psalm 96:5. “To whom then will ye liken Me, or shall I be equal? saith the Holy One. Lift up your eyes on high, and behold who hath created these things.” “Thus saith the Lord that created the heavens; God Himself that formed the earth and made it: … I am the Lord; and there is none else.” Isaiah 40:25, 26; 45:18. Says the psalmist: “Know ye that the Lord He is God: it is He that hath made us, and not we ourselves.” “O come, let us worship and bow down: let us kneel before the Lord our Maker.” Psalm 100:3; 95:6. And the holy beings who worship God in heaven state, as the reason why their homage is due to Him: “Thou art worthy, O Lord, to receive glory and honor and power: for Thou hast created all things.” Revelation 4:11. GC 436.2
In Revelation 14, men are called upon to worship the Creator; and the prophecy brings to view a class that, as the result of the threefold message, are keeping the commandments of God. One of these commandments points directly to God as the Creator. The fourth precept declares: “The seventh day is the Sabbath of the Lord thy God: … for in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the Sabbath day, and hallowed it.” Exodus 20:10, 11. Concerning the Sabbath, the Lord says, further, that it is “a sign, … that ye may know that I am the Lord your God.” Ezekiel 20:20. And the reason given is: “For in six days the Lord made heaven and earth, and on the seventh day He rested, and was refreshed.” Exodus 31:17. GC 437.1
“The importance of the Sabbath as the memorial of creation is that it keeps ever present the true reason why worship is due to God” – because He is the Creator, and we are His creatures. “The Sabbath therefore lies at the very foundation of divine worship, for it teaches this great truth in the most impressive manner, and no other institution does this. The true ground of divine worship, not of that on the seventh day merely, but of all worship, is found in the distinction between the Creator and His creatures. This great fact can never become obsolete, and must never be forgotten.” – J. N. Andrews, History of the Sabbath, chapter 27. It was to keep this truth ever before the minds of men, that God instituted the Sabbath in Eden; and so long as the fact that He is our Creator continues to be a reason why we should worship Him, so long the Sabbath will continue as its sign and memorial. Had the Sabbath been universally kept, man’s thoughts and affections would have been led to the Creator as the object of reverence and worship, and there would never have been an idolater, an atheist, or an infidel. The keeping of the Sabbath is a sign of loyalty to the true God, “Him that made heaven, and earth, and the sea, and the fountains of waters.” It follows that the message which commands men to worship God and keep His commandments will especially call upon them to keep the fourth commandment.
