What does the Bible say about the wrath of God?
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 a 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 78:56-66describes 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 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 wrath.
The New Testament supports the concept of God as a God of wrath who judges sin. It is ultimately manifested in the Tribulation, Hell and the Lake of Fire. 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).
“He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.” John 3:36
Human wrath is warned against in Romans 12:19, Ephesians 4:26, and Colossians 3:8-10. God alone is able to avenge because His vengeance is perfect and holy, whereas man’s wrath is sinful, opening him up to demonic influence. For the Christian, anger and wrath are inconsistent with our new nature, which is the nature of Christ Himself (2 Corinthians 5:17). To realize freedom from the domination of wrath, the believer needs the Holy Spirit to sanctify and cleanse his heart of feelings of wrath and anger.Romans 8 shows victory over sin in the life of one who is living in the Spirit (Romans 8:5-8). Philippians 4:4-7 tells us that the mind controlled by the Spirit is filled with peace.
The wrath of God is a fearsome and terrifying thing. “Much more then, being now justified by his blood, we shall be saved from wrath through him.” Romans 5:9
