The concept of white garments is deeply symbolic in the context of the Great White Throne Judgment. White represents righteousness, purity, and cleanliness, untainted by the sin of the world. This symbolism extends to the throne itself, which is described as white, signifying that the Judge who sits upon it is holy, righteous, and pure. The purity of white also implies joy and happiness, stemming from the knowledge that God accepts the works of those who follow His way. Just as Christ and those who return with Him are depicted as clothed in white, showing their cleanliness and purity, so too does the white throne reflect the perfect and unerring nature of the judgments made from it. Those who come before this throne need not fear an unjust decision, for the One who sits upon it embodies holiness and righteousness, ensuring that every decree is just and proper.

Biblically, white is a color with varied significance. In Ecclesiastes 9:8, Solomon advises, "Let your garments always be white," which is often understood to symbolize the joy, purity, and beauty of a righteous, godly individual. The Shulamite describes her Beloved, a type of Christ, as white in Song of Songs 5:10, suggesting His spotless and holy character. Similarly, Daniel sees the Ancient of Days clothed in a garment white as snow in Daniel 7:9, echoing John's vision of the glorified Christ in Revelation 1:13-16. In Revelation, white predominantly carries positive connotations, often associated with God, Christ, glorified saints, or objects like the Great White Throne, suggesting purity, righteousness, holiness, glory, victory, and perfection. Despite these associations, the white horseman of Revelation 6:1-2, while appearing glorious, embodies a deceptive force, using his whiteness as a façade to conceal a deadly, unholy purpose of conquest through false religious communication.

In the vision described, the souls under the altar, who have endured persecution and martyrdom, are each given a white robe as a symbol of salvation. The white color of the robe signifies purity, righteousness, joy, victory, and perfection, marking their status as redeemed through their suffering. This act precedes God's response to their cry for justice, affirming their ultimate reward despite their current state of rest in death.

At the marriage of the Lamb, the Bride is granted fine linen, clean and white, a privilege far more beautiful, important, and meaningful than even the loveliest physical wedding gown. Revelation 19:8 identifies this linen as the righteous acts of the saints. The Bride will have made herself ready, refusing to let anything sidetrack her preparation. A study of fine, clean, white linen in the Bible shows that this fabric, or more correctly a spiritual version of it, is worn by angels, by royalty, and by God's priests, and it was used extensively in constructing the Tabernacle. God's children who make up the Bride become worthy to wear it because they become like angels (Matthew 22:30) and become kings, priests, and pillars in God's Temple. The Bridegroom, His garment dipped in blood, will descend to earth with His Bride and His angels, all clothed in fine, white, clean linen (Revelation 19:12-16). Those who wish to wear this raiment must prepare diligently now, since the five foolish virgins, who did not adequately prepare, will not be at the Marriage Supper.
