The ark in the tabernacle on earth contained the two tables of stone, upon which were inscribed the precepts of the law of God. The ark was merely a receptacle for the tables of the law, and the presence of these divine precepts gave to it its value and sacredness. When the temple of God was opened in heaven, the ark of His testament was seen. Within the holy of holies, in the sanctuary in heaven, the divine law is sacredly enshrined--the law that was spoken by God Himself amid the thunders of Sinai and written with His own finger on the tables of stone.
The law of God in the sanctuary in heaven is the great original, of which the precepts inscribed upon the tables of stone and recorded by Moses in the Pentateuch were an unerring transcript. Those who arrived at an understanding of this important point were thus led to see the sacred, unchanging character of the divine law. They saw, as never before, the force of the Saviour's words: "Till heaven and earth pass, not one jot or one tittle shall in no wise pass from the law" (Matthew 5:18). (The Great Controversy, 434)
Reflection: The Law of God is a revelation of His character. Since God does not change, His Law will endure forever.
