U- Unveiling the Word

The verb ῥυπαίνω carries profound theological weight in its New Testament usage. While its basic meaning relates to becoming physically dirty or filthy, its appearance in Revelation 22:11 emphasizes the spiritual and moral dimensions of defilement. In this eschatological context, the word describes a fixed state of moral corruption, suggesting that those who persist in unrighteousness will become permanently set in their ways. Early church fathers used this word to warn against moral compromise and emphasize the urgency of repentance. Today, this word continues to challenge believers to examine their spiritual condition and reminds us of the eternal consequences of our moral choices.
