How do we know God is righteous?

The righteousness of God is supremely demonstrated through the person and work of Jesus Christ. In Jeremiah 23:6, the Lord is called 'The Lord Our Righteousness' (Jehovah Sidkenu), indicating that through Christ's perfect life and substitutionary death, God's righteousness is imputed to believers. This truth forms the foundation of historic Reformed theology, highlighting that our right standing before God is based entirely on Jesus’ obedience and sacrifice, rather than on our efforts or merits. God’s nature and His actions affirm His righteousness in both judgment and mercy.
