Was John the Baptist the promised messenger who was to announce Jesus as the King?
Yes. The promised messenger of the covenant is identified as John the Baptist, who would come on the scene to announce the King. That King fulfills the Abrahamic covenant, and John's message was, 'Repent ye, for the kingdom of heaven is at hand.'
Les explains that the promised messenger of the covenant is John the Baptist, who would come on the scene to announce the King. The King is the fulfillment of the Abrahamic covenant, which promised a nation of people, a geographical area of land, and God coming to be their King and Redeemer. The law, Davidic, and Mosaic covenants came later but were all under the Abrahamic covenant. John came preaching in the wilderness of Judea, saying, 'Repent ye, for the kingdom of heaven is at hand.'
