In this installment of Vos Group, Lane Tipton and Camden Bucey discuss pp. 322–329 of Geerhardus Vos’ book, Biblical Theology: Old and New Testaments. In this section, Vos discusses John’s testimony of Jesus after his baptism. The testimony of John the Baptist as depicted in the Gospel of John emphasizes Jesus’ unique divine nature and eternal preexistence, distinguishing him from all others in redemptive history. This underlines John’s role as the one preparing the way for Jesus, who fulfills Old Testament prophecies as the sacrificial Lamb of God. It also highlights the immutable deity of Christ, who, despite his incarnation, remains unchanged in his divine essence. The narrative showcases Jesus’ baptism as an act of vicarious repentance and affirms his authority to bestow the Spirit, underscoring the theological depth of his identity and mission as witnessed by John the Baptist.
