How does God's anger reflect His holiness?

God's anger is an expression of His holiness, underscoring the truth that He cannot tolerate sin. Isaiah states that God's holiness requires punishment for transgressions, and to ignore sin would diminish His just character. He is exalted in judgment and will be sanctified in righteousness (Isaiah 5:16). When God’s wrath is revealed, it honors His integrity—showing that while He is merciful and loving, He is also just and must deal with sin seriously. This reflection of His holiness is what leads us to appreciate the grace offered through Christ profoundly.
