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

Scripture reveals that God's anger and wrath are intricately linked to His holy nature. In Exodus 34:7, we see that God will not leave the guilty unpunished, illustrating His righteousness in response to sin. Moses, in Psalm 90, highlights the seriousness of sin and reminds us that we are consumed by God's anger due to our iniquity. The justification for His anger stems from His holiness, which abhors sin and cannot coexist with it. Understanding God's wrath is crucial for recognizing the depth of our need for salvation and mercy through Christ.
