How do we know that God's anger and wrath are justified?

Psalm 90 presents a sobering view of God's anger in relation to human sin. The psalmist points out that God's wrath is a response to our iniquities, highlighting that our secret sins are laid bare before Him (Psalm 90:8). This serves as a reminder that God's holiness cannot tolerate sin, and thus, His anger is both righteous and justified. Humans, as created beings, are accountable to their Creator for their transgressions. The message of Scripture underscores that it is through recognizing our transgressions and seeking God's mercy in Christ that we can find reconciliation and hope.
