How do we know God's judgment is just?

God's judgment is depicted as perfectly just throughout Scripture, primarily because He judges according to the heart and the intentions within (James 4:11). Unlike human judgment, which can often be biased or swayed by external appearances, God's judgment reflects the true nature and reality of each man's actions. Revelation 18:6 emphasizes that God rewards each according to their works, ensuring that no unjust action goes unnoticed. The justice of God is vital not only because it maintains equity in His creation but also serves as a reminder that all are accountable before Him. In God's justice, there exists a reminder for believers that the mercy they have received through Christ must compel them to show mercy to others, lest they themselves be judged without mercy (James 2:13).
