The Bible teaches that God will be glorified in His saints the day of His return, but Psalm 76:10 also says that “Surely the wrath of man shall praise you; the remnant of wrath you will put on like a belt.” Proverbs 16:4 states that “The Lord has made everything for its purpose, even the wicked for the day of trouble.” What good purpose could come from the terrible day of judgement that will fall upon wicked people? What type of praise will God receive for having executed his wrath upon men?
Romans 9:22-23 “What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, in order to make known the riches of his glory for vessels of mercy which he has prepared beforehand for glory…?”
God Almighty is not ashamed of His attributes. He desires to make known His mercy, but also to be revealed as great in wrath, awesome in power, and just to punish.
In David’s prayer of repentance after committing adultery with Bathsheba he says “Against you, you only have I sinned and done what is evil in your sight, so that you may be justified in your words and blameless in your judgement (Psalm 51:4).” We know that God does not need to be “justified” in a sense like we do, but rather this word means He will be shown as righteous and just, and will make manifest what He already is. Our sin brings us guilt that is like a rotting in our bones. It can tear apart families and leads us down the road to death. All of sin’s results, including final judgement will cause men to be undeniably sure that all of God’s judgements and words were blameless.
Paul quotes Psalm 51:4 and brings up this argument: “But if our unrighteousness serves to show the righteousness of God, what shall we say? That God is unrighteous to inflict wrath on us? (I speak in a human way.) By no means! For then how could God judge the world (Romans 3:5-6)?”
This is ample evidence to show God desires to show forth His justice, and that He will be right and fair in doing so. When we accuse God of being unfair, we elevate ourselves above God and are actually considering that God may be unrighteous. God’s plan and execution of redemption and judgement is perfect. At the final judgement the redeemed will glorify God for dealing perfect justice, and their praises will be exalted higher upon the visual realization of what they have been spared from.
