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.
The 2300 days had been found to begin when the commandment of Artaxerxes for the restoration and building of Jerusalem went into effect, in the autumn of 457 B.C. Taking this as the starting point, there was perfect harmony in the application of all the events foretold in the explanation of that period in Daniel 9:25-27.... The seventy weeks, or 490 years, were to pertain especially to the Jews. At the expiration of this period, the nation sealed its rejection of Christ by the persecution of His disciples, and the apostles turned to the Gentiles, A.D. 34. The first 490 years of the 2300 having then ended, 1810 years would remain. From A.D. 34, 1810 years extend to 1844. “Then,” said the angel, “shall the sanctuary be cleansed.”
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. FLB 208
If trials increase upon them, they may know that God is testing and proving their fidelity. And in just that degree that they maintain their integrity of character under discouragements, will their fortitude, stability, and power of endurance increase, and they wax strong in spirit. Pr 162
And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed. Daniel 8:14 (King James Version)
