In their investigation they learned that the earthly sanctuary, built by Moses at the command of God according to the pattern shown him in the mount, was “a figure for the time then present, in which were offered both gifts and sacrifices”; that its two holy places were “patterns of things in the heavens”; that Christ, our great High Priest, is “a minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man”; that “Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us.” Hebrews 9:9, 23; 8:2; Hebrews 9:24. SR 376.2
The sanctuary in heaven, in which Jesus ministers in our behalf, is the great original, of which the sanctuary built by Moses was a copy. As the sanctuary on earth had two apartments, the holy and the most holy, so there are two holy places in the sanctuary in heaven. And the ark containing the law of God, the altar of incense, and other instruments of service found in the sanctuary below, have also their counterpart in the sanctuary above. In holy vision the apostle John was permitted to enter heaven, and he there beheld the candlestick and the altar of incense, and as “the temple of God was opened,” he beheld also “the ark of His testament.” Revelation 4:5; 8:3; Revelation 11:19. SR 377.1
Those who were seeking for the truth found indisputable proof of the existence of a sanctuary in heaven. Moses made the earthly sanctuary after a pattern which was shown him. Paul declared that that pattern was the true sanctuary which is in heaven. (Hebrews 8:2, 5.) John testified that he saw it in heaven. SR 377.2
At the termination of the 2300 days, in 1844, no sanctuary had existed on earth for many centuries; therefore the sanctuary in heaven must be the one brought to view in the declaration, “Unto two thousand and three hundred days; then shall the sanctuary be cleansed.” But how could the sanctuary in heaven need cleansing? Turning again to the Scriptures, the students of prophecy learned that the cleansing was not a removal of physical impurities, for it was to be accomplished with blood, and therefore must be a cleansing from sin. Thus says the apostle: “It was therefore necessary that the patterns of things in the heavens should be purified with these [the blood of animals]; but the heavenly things themselves with better sacrifices than these [even the precious blood of Christ].” Hebrews 9:23. SR 377.3
To obtain a further knowledge of the cleansing to which the prophecy points, it was necessary to understand the ministration of the heavenly sanctuary. This could be learned only from the ministration of the earthly sanctuary; for Paul declares that the priests who officiated there served “unto the example and shadow of heavenly things.” Hebrews 8:5.
