The Investigative Judgment is a central doctrine in the writings of Ellen G. White and is a key teaching in Seventh-day Adventist theology. According to her books, the Investigative Judgment is a process that takes place in the courts of heaven while people are still living on earth. During this time, the lives of all professed followers of Christ are reviewed before God. Each person is examined according to the records in the books of heaven, and their destiny is forever fixed based on their deeds (see Christ’s Object Lessons, p. 310). This judgment is described as the "closing work in the sanctuary above." It is a process of examining character to determine who is prepared for the kingdom of God. Ellen White illustrates this with the parable in Matthew 22, where the king examines the guests to see if they are wearing the wedding garment, which symbolizes a character washed in the blood of the Lamb (see The Great Controversy, p. 428). The work of the Investigative Judgment and the blotting out of sins must be completed before the second coming of Christ. The sins of believers are blotted out when the times of refreshing come from the presence of the Lord, and Jesus returns (see The Great Controversy, p. 485). When the Investigative Judgment closes, the destiny of every person is decided for life or death. Probation ends shortly before Christ appears in the clouds of heaven. At that time, the pronouncement is made: “He that is unjust, let him be unjust still... and he that is righteous, let him be righteous still...” (Revelation 22:11, 12; see The Great Controversy, p. 490). Ellen White emphasizes that the subject of the sanctuary and the Investigative Judgment should be clearly understood by God's people. Each person has a case pending at the bar of God and must meet the great Judge face to face. It is important for everyone to contemplate the solemn scene when the judgment sits and the books are opened (see The Great Controversy, p. 488). In summary, the Investigative Judgment is the heavenly process of reviewing the lives of all who have professed faith in Christ, determining their fitness for heaven, and blotting out the sins of the righteous before Christ's return. It is closely tied to the sanctuary doctrine and the Second Advent in Ellen White's writings. References: - White, E. G. (1900). Christ’s Object Lessons, p. 310. - White, E. G. (1911).
