Zechariah 14:9

And the Lord shall be King over all the earth: in that day shall there be one Lord, and his name One.

Here again surely the spiritual kingdom of the Lord Jesus is plainly marked. In the present hour, what endless varieties of sects, even among Christians, do we meet with. But, when this blessed period shall arrive, Jesus will be the one Universal Monarch, and his dominion from sea to sea, and from the river to the ends of the earth. Psalms 72:8. And what is beautifully connected with this view of Christ's universal kingdom, is, the glorious doctrine of the Unity of the Godhead, existing in the threefold character of person, Father, Son, and Holy Ghost, will be the religion of the whole earth. For it is said, the earth shall be full of the knowledge of the Lord, as the waters cover the sea. Isaiah 11:9.
