Why is it important to understand God's judgment against sin?

The concept of God's judgment against sin is foundational to the Christian faith because it underscores the severity of sin and the high cost of redemption. As described in Isaiah 63, God's vengeance is portrayed as a righteous response to evil, emphasizing His holiness and justice. Recognizing the penalty of sin helps believers appreciate the grace they receive through Jesus Christ, who bears the wrath for those who believe in Him. This understanding ignites a deeper appreciation for God's mercy and encourages believers to pursue a life characterized by holiness, as they are set free from the bondage of sin and empowered to live righteously through Christ.
