How do we know Christ is the Son of Righteousness?

The identification of Christ as the Son of Righteousness is firmly established in both the Old and New Testaments. In the New Testament, Jesus directly claims to be the light of the world (John 8:12), correlating with the description of the Son of Righteousness as a source of spiritual illumination and healing. Additionally, references made by John the Baptist affirm that he came to prepare the way for Jesus, who was prophesied to be the Messiah. Various Gospel accounts link the prophecies in Malachi directly to Christ's ministry and identity, reinforcing the claim of His righteous nature and redemptive purpose.
