But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, ...And after the second veil, the tabernacle which is called the Holiest of all;...But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people....And he said unto me, Unto two thousand and three hundred days (years); then shall the sanctuary be cleansed.
Hebrews 9:11,3,7/Daniel 8:14
"....the present test on the Sabbath could not come, until the 
mediation of Jesus in the Holy Place was finished; and He had passed within the second veil;
---therefore, Christians, who fell asleep before the door was opened in the Most Holy, .... and had not kept the true Sabbath, now rest in hope; for they had not the light, and the test on the Sabbath, which we now have, since that door was opened..... Satan was tempting some of God's people on this point.
Because so many good Christians have fallen asleep in the triumphs of faith, and have not kept the true Sabbath, they were doubting about it being a test for us now."
E.G.W.
