What does the Bible say about God's anger and mercy?

The Bible presents God as a balance of justice and mercy. In Nahum 1:6, it is stated that God is angry with the wicked, highlighting the seriousness of sin and divine justice. Yet, this same God is characterized by mercy, as He invites the unrighteous to forsake their ways and return to Him, promising abundant pardon (Isaiah 55:7). This duality emphasizes that while God will not acquit the wicked (Nahum 1:3), He demonstrates His mercy through the redeeming work of Christ, who took upon Himself the wrath meant for sinners.
