Wrath is defined as “the emotional response to perceived wrong and injustice,” often translated as “anger,” “indignation,” “vexation,” or “irritation.” Both humans and God express wrath. But there is vast difference between the wrath of God and the wrath of man. God’s wrath is holy and always justified; man’s is never holy and rarely justified.
In the Old Testament, the wrath of God is a divine response to human sin and disobedience. Idolatry was most often the occasion for divine wrath. Psalm 78:56-66 describes Israel’s idolatry. The wrath of God is consistently directed towards those who do not follow His will (Deuteronomy 1:26-46; Joshua 7:1; Psalm 2:1-6). The Old Testament prophets often wrote of a day in the future, the "day of wrath" (Zephaniah 1:14-15). God’s wrath against sin and disobedience is perfectly justified because His plan for mankind is holy and perfect, just as God Himself is holy and perfect. God provided a way to gain divine favor—repentance—which turns God’s wrath away from the sinner. To reject that perfect plan is to reject God’s love, mercy, grace and favor and incur His righteous wrath.
In the New Testament, Jesus’ teachings support the concept of God as a God of wrath who judges sin. The story of the rich man and Lazarus speaks of the judgment of God and serious consequences for the unrepentant sinner (Luke 16:19-31). Jesus said in John 3:36, "Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on Him." The one who believes in the Son will not suffer God’s wrath for his sin, because the Son took God’s wrath when He died in our place on the cross (Romans 5:6-11). Those who do not believe in the Son, who do not receive Him as Savior, will be judged on the day of wrath (Romans 2:5-6).
