“Blessed is he who comes in the name of the Lord” is a declaration of praise and recognition that Jesus Christ is the Savior of the world who came in the power and authority of God. “I have come in my Father’s name,” said Jesus (John 5:43). All that Christ did was commissioned by His Father. Everything Jesus said and did was to glorify His Father and accomplish the work of making Him known to humans so that they might be saved (John 17:1–24).
