Sanctuary

"But such subjects as the sanctuary, in connection with the 2300 days, the commandments of God and the faith of Jesus, are perfectly calculated to explain the past Advent movement and show what our present position is, establish the faith of the doubting, and give certainty to the glorious future. These, I have frequently seen, were the principal subjects on which the messengers should dwell." Early Writings, p. 63 (Ellen G. White).

Sanctuary Gone Atonement Gone -- "In a representation which passed before me, I saw a certain work being done by medical missionary workers. Our ministering brethren were looking on, watching what was being done, but they did not seem to understand. The foundation of our faith, which was established by so much prayer, such earnest searching of the Scriptures, was being taken down, pillar by pillar. Our faith was to have nothing to rest upon--the sanctuary was gone, the atonement was gone." E.G. White, The Upward Look, 152.
