The historic belief of the church and the clear biblical evidence is that the supernatural power of Jesus came through the Holy Spirit. Before his baptism, where the Holy Spirit descended on him “like a dove,” Jesus lived thirty years, and as far as we know he didn’t utter a word of teaching, work a miracle, or recruit a disciple. After his baptism, Jesus was constantly teaching, working miracles, and calling disciples. His baptism was the inciting incident that started it all.
