In a related sense, God’s holiness is also seen in judgment on sin. When the Bible speaks (as it does in 2 Thessalonians 1:7, for example) of Jesus’ coming in flaming fire and taking vengeance on those who do not know God and do not obey the gospel; and when it describes (as in Jude 15) the condemnation of the ungodly, we see how God hates sin.
