Commentators emphasize that Jesus began his public ministry "in the power of the Spirit." This wasn't just a title, but a dynamic, active force (the Greek word is dynamis, the root of "dynamite"). Scholars note this marks a new phase in his work, empowered for teaching and miracles. As one commentator points out, if Jesus, the Son of God, relied on the Spirit's power for ministry, how much more should believers seek it?
