The passing of the time in 1844 was followed by a period of great trial to those who still held the advent faith. Their only relief, so far as ascertaining their true position was concerned, was the light which directed their minds to the sanctuary above. Some renounced their faith in their former reckoning of the prophetic periods and ascribed to human or satanic agencies the powerful influence of the Holy Spirit which had attended the advent movement. Another class firmly held that the Lord had led them in their past experience; and as they waited and watched and prayed to know the will of God they saw that their great High Priest had entered upon another work of ministration, and, following Him by faith, they were led to see also the closing work of the church. They had a clearer understanding of the first and second angels’ messages, and were prepared to receive and give to the world the solemn warning of the third angel of Revelation 14.... 3AM 75.2
... Those who by faith followed their great High Priest as He entered upon His ministry in the most holy place, beheld the ark of His testament. As they had studied the subject of the sanctuary they had come to understand the Saviour’s change of ministration, and they saw that He was now officiating before the ark of God, pleading His blood in behalf of sinners. 3AM 76.1
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. 3AM 76.2
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, one jot or one tittle shall in no wise pass from the law.” Matthew 5:18. The law of God, being a revelation of His will, a transcript of His character, must forever endure, “as a faithful witness in heaven.” Not one command has been annulled; not a jot or tittle has been changed. Says the psalmist: “Forever, O Lord, Thy word is settled in heaven.” “All His commandments are sure. They stand fast for ever and ever.” Psalm 119:89; 111:7, 8. 3AM 76.3
In the very bosom of the Decalogue is the fourth commandment, as it was first proclaimed: “Remember the Sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work: but the seventh day is the Sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 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 20:8-11. 3AM 77.1
The Spirit of God impressed the hearts of those students of His word. The conviction was urged upon them that they had ignorantly transgressed this precept by disregarding the Creator’s rest day. They began to examine the reasons for observing the first day of the week instead of the day which God had sanctified. They could find no evidence in the Scriptures that the fourth commandment had been abolished, or that the Sabbath had been changed; the blessing which first hallowed the seventh day had never been removed. They had been honestly seeking to know and to do God’s will; now, as they saw themselves transgressors of His law, sorrow filled their hearts, and they manifested their loyalty to God by keeping His Sabbath holy. 3AM 77.2
Many and earnest were the efforts made to overthrow their faith. None could fail to see that if the earthly sanctuary was a figure or pattern of the heavenly, the law deposited in the ark on earth was an exact transcript of the law in the ark in heaven; and that an acceptance of the truth concerning the heavenly sanctuary involved an acknowledgment of the claims of God’s law and the obligation of the Sabbath of the fourth commandment. Here was the secret of the bitter and determined opposition to the harmonious exposition of the Scriptures that revealed the ministration of Christ in the heavenly sanctuary. Men sought to close the door which God had opened, and to open the door which He had closed. But “He that openeth, and no man shutteth; and shutteth, and no man openeth,” had declared: “Behold, I have set before thee an open door, and no man can shut it.” Revelation 3:7, 8. Christ had opened the door, or ministration, of the most holy place, light was shining from that open door of the sanctuary in heaven, and the fourth commandment was shown to be included in the law which is there enshrined; what God had established, no man could overthrow. 3AM 77.3
Those who had accepted the light concerning the mediation of Christ and the perpetuity of the law of God found that these were the truths presented in Revelation 14. The messages of this chapter constitute a threefold warning which is to prepare the inhabitants of the earth for the Lord’s second coming.—The Great Controversy, 431-435 (1888, 1911) 3AM 78.1
