WLC Q.89: What shall be done to the wicked at the day of judgment?
At the day of judgment, the wicked shall be set on Christ’s left hand, (Matt. 25:33) and, upon clear evidence, and full conviction of their own consciences, (Rom. 2:15–16) shall have the fearful but just sentence of condemnation pronounced against them; (Matt. 25:41–43) and thereupon shall be cast out from the favourable presence of God, and the glorious fellowship with Christ, his saints, and all his holy angels, into hell, to be punished with unspeakable torments, both of body and soul, with the devil and his angels for ever. (Luke 16:26, 2 Thess. 1:8–9)
WCF 33.2.
The end of God’s appointing this day is for the manifestation of the glory of His mercy, in the eternal salvation of the elect; and of His justice, in the damnation of the reprobate, who are wicked and disobedient. For then shall the righteous go into everlasting life, and receive that fullness of joy and refreshing, which shall come from the presence of the Lord: but the wicked, who know not God, and obey not the Gospel of Jesus Christ, shall be cast into eternal torments, and be punished with everlasting destruction from the presence of the Lord, and from the glory of His power. (Matt. 25:31–46, Rom. 2:5–6, Rom. 9:22–23, Matt. 25:21, Acts 3:19, 2 Thess. 1:7–10)
