What does it mean that Christ is the just one?

In Christian theology, Christ is referred to as the 'just one' as he fulfills the requirements of justice and righteousness that no man can. This is seen in 2 Samuel 23:3, where it states that anyone who rules must be just. Christ's life and sacrifice represent the ultimate expression of justice, as He bore the sins of His people and provided a way for them to be justified before God. By His perfect obedience and atoning death, all who believe in Him are seen as righteous in God's sight, showcasing the depth of divine mercy and justice.
