What does it mean for God to be just?

God's justice is a critical aspect of His character, as highlighted in Exodus 34 when He states that He will 'by no means clear the guilty.' This means that while God is merciful, His mercy does not compromise His justice. True justice requires a balance where sin is addressed and dealt with appropriately. This aspect of God's nature ensures that He does not overlook wrongdoing but rather provides a means of forgiveness through Christ, which upholds His perfect justice and mercy simultaneously.
