God’s anger is not capricious or unjust. Instead His anger is purposeful, resulting in a thoughtful plan and process to reconcile all injustice. In short, it’s good. God’s ultimate aim in displaying His anger is the demonstration of the glory of His justice. He delights in being a righteous and just God. Through and through God is fully righteous, thus any unrighteousness provokes his wrath. However, that is not all God is. God is love and God’s love also demands His wrath. As David Powlison has put it, “You can’t understand God’s love if you don’t understand his anger.”[2]
Understanding God’s anger inevitably leads us to the cross where God’s justice and mercy meet in perfect, soul-wrenching, Christ-crushing, sin-forgiving, life-giving harmony. The anger of God against our unrighteousness was mercifully diverted from us onto His beloved Son. As a result, God preserved and promoted both His justice and humanity’s joy through the cross. Thus, God’s penultimate aim in His anger is the good of the elect, revealing the two-sided purpose of his wrath, His glory and our good. Briefly put, the purpose of God’s anger is to display the depth and character of his eternal justice and love.
The plan for the outworking of God’s wrath results in two main ends, salvation or condemnation. For those who hope in Christ for the forgiveness of their transgressions, salvation waits; but for those who hope in the world, the self, or other plans, only condemnation awaits. The only plan that fuels God’s purpose to glorify His justice and satisfy our need for love is the Gospel. The plan began at creation, finding redemptive expression through new creation and culmination in His consummation of all things. This plan operates through the process of cultivation, the cultivation of sinners made new, day by day, demonstrating that God is for us, not against us.
But what of our anger? What is the difference between God-imitating, righteous anger and self-glorifying sinful anger? Is anger just violent outbursts and wife-beating or can it take more subtle forms? How are we to be made new in the battle against anger?
