How do we know God's justice and mercy are compatible?

God is both just and merciful, and this is crucial to understanding the character of our Creator. His justice demands that sin be punished, but His mercy provides a way for sinners to be redeemed. This compatibility is most clearly shown in the work of Jesus Christ. Romans 3:26 states that God is 'just and the justifier of the one who has faith in Jesus.' God’s justice is not compromised; rather, it is fulfilled through the sacrifice of Christ, who bears the penalty for sin. Thus, while He punishes sin, He also provides redemption for those who trust in His Son, showcasing His mercy and grace.
