Revelation 19:6 (ESV) … “Then I heard what seemed to be the voice of a great multitude, like the roar of many waters and like the sound of mighty peals of thunder, crying out, “Hallelujah! For the Lord our God the Almighty reigns.”
This passage refers to that blessed day that is yet to come when all opposition to Christ has been eliminated from the earth, when Babylon has been cast into the sea of God’s wrath. It refers to that day when ‘The kingdoms of this world become the kingdoms of our Lord and his Christ’, when the knowledge of the Lord will cover the earth as the waters cover the sea, and ‘Nations shall learn war no more.’
But the doctrine taught in our text is a blessed truth in all ages: ‘The Lord God omnipotent reigneth!’ Forever, before the worlds were made and forever after the worlds are dissolved, at all times and in all places, from the beginning to the end, ‘The Lord God omnipotent reigneth!’ All God’s saints, in all ages, rejoice to sing with unison this great Hallelujah chorus: ‘Alleluia, for the Lord God omnipotent reigneth!’
The object of Christ in his sovereign, universal rule of all things is the eternal good of his elect (Rom. 8:28). ‘The Lord God omnipotent reigneth,’ so that he may accomplish his eternal purpose of grace towards his chosen, redeemed people (John 17:2). Let him do what he deems good, for what he does is good, always good, only good and eternally good for his elect. How we ought to trust him! (Prov. 3:4–6). He loves us. He lived for us. He died for us. He reigns for us. We can trust a King whose throne is erected and dedicated for our good!
