How do we understand God's justice in relation to His mercy?

The harmony between God's justice and mercy is a profound aspect of Reformed theology. God is a just God who must hold sin accountable; as it states in Romans 3:26, He is 'just and the justifier of the one who has faith in Jesus.' Through the sacrifice of Christ, God's justice is satisfied as the penalty for sin is fully paid while His mercy is extended to sinners who believe. The sermon highlights that God's judgments are deep and unfathomable, indicating His sovereign control over all things, including salvation. Therefore, when believers place their trust in Christ, they are not only recipients of His mercy but are assured of God's justice being satisfied, demonstrating that He can save us justly without violating His holy character.
