God is just in forgiving sin because His justice is upheld through the sacrifice of Christ, which satisfies the penalty for sin.
God’s justice is intricately tied to the nature of His forgiveness. Romans 3:25-26 reveals that God demonstrated His righteousness by setting forth Christ as a propitiation, satisfying His wrath against sin. This divine justice is not compromised when God forgives sin; rather, it is fulfilled through the perfect sacrifice of His Son. Without such a sacrifice, forgiveness would undermine His holiness and justice. The beauty of the cross is that it showcases how God can simultaneously uphold the demands of justice while extending grace and mercy to sinners, thereby assuring believers that His forgiveness does not disregard His righteousness but rather affirms it.
