All who have received the light upon these subjects are to bear testimony of the great truths which God has committed to them. The sanctuary in heaven is the very center of Christ’s work in behalf of men. It concerns every soul living upon the earth. It opens to view the plan of redemption, bringing us down to the very close of time, and revealing the triumphant issue of the contest between righteousness and sin. It is of the utmost importance that all should thoroughly investigate these subjects, and be able to give an answer to every one that asketh them a reason of the hope that is in them.—The Great Controversy, 488, 489 (1888). (Ev 222.1) MC VC

The Key to a Complete System of Truth—The subject of the sanctuary was the key which unlocked the mystery of the disappointment of 1844. It opened to view a complete system of truth, connected and harmonious, showing that God’s hand had directed the great advent movement, and revealing present duty as it brought to light the position and work of His people.—The Great Controversy, 423, (1888). (Ev 222.2) MC VC

Eyes Fixed on Sanctuary—As a people, we should be earnest students of prophecy; we should not rest until we become intelligent in regard to the subject of the sanctuary, which is brought out in the visions of Daniel and John. This subject sheds great light on our present position and work, and gives us unmistakable proof that God has led us in our past experience. It explains our disappointment in 1844, showing us that the sanctuary to be cleansed was not the earth, as we had supposed, but that Christ then entered into the most holy apartment of the heavenly sanctuary, and is there performing the closing work of His priestly office, in fulfillment of the words of the angel to the prophet Daniel, “Unto two thousand and three hundred days; then shall the sanctuary be cleansed.” Daniel 8:14. (Ev 222.3) MC VC

Our faith in reference to the messages of the first, second, and third angels was correct. The great waymarks we have passed are immovable. Although the hosts of hell may try to tear them from their foundation, and triumph in the thought that they have succeeded, yet they do not succeed. These pillars of truth stand firm as the eternal hills, unmoved by all the efforts of men combined with those of Satan and his host. We can learn much, and should be constantly searching the Scriptures to see if these things are so. God’s people are now to have their eyes fixed on the heavenly sanctuary, where the final ministration of our great High Priest in the work of the judgment is going forward,—where He is interceding for His people.—The Review and Herald, November 27, 1883. (Ev 223.1) MC VC

The Central Truth in a Simple Theology—In every school established the most simple theory of theology should be taught. In this theory, the atonement of Christ should be the great substance, the central truth. The wonderful theme of redemption should be presented to the students.—Manuscript 156, 1898. (Ev 223.2) MC VC
