This subject was not understood by Adventists in 1844. After the passing of the time when the Saviour was expected, they still believed His coming to be near; they held that they had reached an important crisis and that the work of Christ as man’s intercessor before God had ceased. It appeared to them to be taught in the Bible that man’s probation would close a short time before the actual coming of the Lord in the clouds of heaven. This seemed evident from those scriptures which point to a time when men will seek, knock, and cry at the door of mercy, and it will not be opened. And it was a question with them whether the date to which they had looked for the coming of Christ might not rather mark the beginning of this period which was immediately to precede His coming. Having given the warning of the judgment near, they felt that their work for the world was done, and they lost their burden of soul for the salvation of sinners, while the bold and blasphemous scoffing of the ungodly seemed to them another evidence that the Spirit of God had been withdrawn from the rejecters of His mercy. All this confirmed them in the belief that probation had ended, or, as they then expressed it, “the door of mercy was shut.” (GC 429.1) MC VC

But clearer light came with the investigation of the sanctuary question. They now saw that they were correct in believing that the end of the 2300 days in 1844 marked an important crisis. But while it was true that that door of hope and mercy by which men had for eighteen hundred years found access to God, was closed, another door was opened, and forgiveness of sins was offered to men through the intercession of Christ in the most holy. One part of His ministration had closed, only to give place to another. There was still an “open door” to the heavenly sanctuary, where Christ was ministering in the sinner’s behalf. (GC 429.2) MC VC
