How does mercy relate to God's justice?

The sermon highlights that mercy is not mandatory; God's justice requires Him to deal with sin. However, when He extends mercy, it does not absolve Him from justice. Instead, God’s justice is satisfied through the sacrificial work of Christ, who bore the sins of those He chose to save. This understanding ensures that God's act of mercy is grounded in righteousness, demonstrating His character as both just and merciful. It underlines the essential aspect of God's grace as not only undeserved favor but also as an act that fulfills the demands of His justice.
