Arthur Just makes the simple observation that ἐξουσίᾳ (authority) is used in Luke 4:32 and 4:36. The first connects Jesus’ authority with his words/teaching and the second connects it with his miracles. Jesus’ words cannot be separated from his miracles. The Word of the Lord does not return void. His Word changes the natural composition of the world every time it is proclaimed. His Word cuts asunder; performs divine surgery on frail men who is then put back together in a profoundly whole and restored fashion. The Word of God is nothing short of miraculous.
