What does the Bible say about God's anger towards the wicked?

The Scriptures emphasize God's righteous anger towards those who refuse to follow Him. Psalm 21 clearly illustrates that it is God's right to judge the wicked, demonstrating that their destruction is not arbitrary but based on their own sinful actions. God does not merely react to sin; rather, He has decreed judgment against the wicked as part of His perfect justice. This means that God, in His sovereignty, has ordained the consequences of wickedness, which leads to the ultimate destruction of those who oppose Him. The fact that He is angry with the wicked every day speaks to His nature as a holy and just God who must respond to sin with justice.
