If everything was finished at the cross, then much of the Hebrew sacrificial service was unnecessary. Then everything was really finished when the animal died on the altar. Why, then, was the rest of the service carried out, where the priest carried the blood into the Holy Place, and performed the Day of Atonement service at the end of the year? If the antitype was completed with the death of the sacrifice, why did the type continue well beyond that? They must agree, or the whole thing falls into a shambles and God is guilty of being the author of confusion. (e.g. 1 Cor. 14:33) As M.L. Andreasen said in Letters to the Churches, what has Jesus been doing since A.D. 31? Pleading with the Father in our behalf for something we already have? The whole concept is ridiculous, and doesn't line up with a great many passages of Scripture and SoP.
Here's Andreasen:

Hear again:
"He who through His own atonement provided for them an infinite fund of moral power will not fail to employ this power in their behalf. He will impute to them His own righteousness.... There is an inexhaustible fund of perfect obedience accruing from His obedience. . . as sincere humble prayers ascend to the throne of God Christ mingles with them the merits of His own life of perfect obedience. Our prayers are made fragrant by this incense. Christ has pledged Himself to intercede in our behalf and the Father hears His Son." - Ibid. [General Conference Bulletin, Vol. 3, pp. 101, 102, Fourth Quarter, 1899.]
When we pray in this very year of 1959 Christ intercedes for us and mingles with our prayers "the merits of His own life of perfect obedience. Our prayers are made fragrant by this incense . . . and the Father always hears His Son."
Contrast this with the statement in Questions on Doctrine page 381: "(Jesus) appeared in the presence of God for us . . . But it was not with the hope of obtaining something for us at that time or at some future time. No! He had already obtained it for us on the cross." (Emphasis his.) Note the picture: Christ appears in the presence of God for us. He pleads but He gets nothing. For 1800 years He pleads and gets nothing. Does He not know that He already has it? Will no one inform Him that it is useless to plead? He Himself has "no hope" of getting anything now or at any future time. And yet He pleads and keeps on pleading. What a sight for the angels! And this is represented to be Adventist teaching! This is the book that has the approval of Adventist leaders and is sent out to the world to show what we believe. May God forgive us. How can we stand before the world and convince any one that we believe in a Savior who is mighty to save when we present Him as pleading in vain before the Father?
But thank God this is not Adventist doctrine. Hear this from Sister White as quoted above: "Christ has pledged Himself to intercede in our behalf and the Father always hears His Son." This is Christianity and the other is not.

The intercession of Christ in man's behalf in the sanctuary above is as essential to the plan of salvation as was His death upon the cross. By His death He began that work which after His resurrection He ascended to complete in heaven.
