"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, pp. 488, 489 E.G.W.
