What does the Bible say about the just man?

In the context of Proverbs 4:18, the just man is identified as Jesus Christ, the only begotten Son of God. He is the embodiment of righteousness and obedience, having lived a perfect life according to God's commandments. Jesus' obedience is essential for our justification, as He is the only one who fulfilled the law of God completely. His journey was marked by perfect submission to the Father, and through His actions, He illustrates what it means to be just and righteous before God. As believers are united with Christ, they too are declared just by faith in Him.
