In the parable of Matthew 22 the same figure of the marriage is introduced, and the investigative judgment is clearly represented as taking place before the marriage. Previous to the wedding the king comes in to see the guests, to see if all are attired in the wedding garment, the spotless robe of character washed and made white in the blood of the Lamb. Matthew 22:11; Revelation 7:14. He who is found wanting is cast out, but all who upon examination are seen to have the wedding garment on are accepted of God and accounted worthy of a share in His kingdom and a seat upon His throne. This work of examination of character, of determining who are prepared for the kingdom of God, is that of the investigative judgment, the closing of work in the sanctuary above. (GC 428.1) 2 I MC VC

When the work of investigation shall be ended, when the cases of those who in all ages have professed to be followers of Christ have been examined and decided, then, and not till then, probation will close, and the door of mercy will be shut. Thus in the one short sentence, “They that were ready went in with Him to the marriage: and the door was shut,”(Matthew 25:10) we are carried down through the Saviour’s final ministration, to the time when the great work for man’s salvation shall be completed. (GC 428.2) MC VC

In the service of the earthly sanctuary, which, as we have seen, is a figure of the service in the heavenly, when the high priest on the Day of Atonement entered the most holy place, the ministration in the first apartment ceased. God commanded: “There shall be no man in the tabernacle of the congregation when he goeth in to make an atonement in the holy place, until he comes out.” Leviticus 16:17. So when Christ entered the holy of holies to perform the closing work of the atonement, He ceased His ministration in the first apartment. But when the ministration in the first apartment ended, the ministration in the second apartment began. When in the typical service the high priest left the holy on the Day of Atonement, he went in before God to present the blood of the sin offering in behalf of all Israel who truly repented of their sins. So Christ had only completed one part of His work as our intercessor, to enter upon another portion of the work, and He still pleaded His blood before the Father in behalf of sinners.

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
