What does walking in white mean in the Bible?

In Revelation 3:4-5, walking in white represents the holiness and purity bestowed upon believers who are justified by faith in Christ. The white garments signify the imputed righteousness of Christ, allowing believers to stand before God clean and accepted. This imagery of white robes is echoed in Revelation 19:8, where the fine linen represents the righteous acts of the saints. The promise that those who overcome will be clothed in white indicates not merely a position of status but a deep spiritual reality where believers are covered by the righteousness of Christ, demonstrating their worthiness to receive eternal life.
