Zechariah 14:9

And the Lord shall be king over all the earth - Such should be the influence of the living water, that is, of the Spirit of God. God who has ever reigned and will reign, “a great King over all the earth” Psalms 47:3, Psalms 47:8, shall be owned by His creatures, as what He is.

There shall be one Lord - More exactly, “The Lord shall be One, and His Name One.” He had before prophesied, “I will cut off the names of the idols out of the land” Zechariah 13:2. The Church being thus cleansed, no other lord or object of worship should be named but “Himself.” This is one of those prophecies, of continued expansion and development, ever bursting out and enlarging, yet never, until the end, reaching its full fulfillment. Dionysius: “Since in this life we contemplate God in His effects, in which His whole perfection shineth not forth now we know Him obscurely and imperfectly, His perfections being in divers diversely represented. In our home we shall see Him as He is, face to Face, through His Essence. Therefore then He will be represented by one name, as He shall be beheld by one gaze.”
