Verses four to six reiterate the praise of heaven. All the elders, and living ones (four beasts) and the mighty multitudes of heaven, shout with one voice, like the roar of the ocean and the roll of thunder, saying: "Alleluia, for the Lord God omnipotent reigneth." Yes, the Lord reigneth, let it be uttered with the voice of many waters, and the roll of mighty thunders till all the earth hears and understands. The devil may rage, and the beast may fight, and the false prophet may join hands with both, and the harlot may entice and seduce, but all of them together are no match for the Lord, they only show their impotence in conflict with the Almighty. Wickedness may rear its head to the skies; persecution may exploit her blandishments; deteriorating and disintegrating forces may be at work; but the Lord still lives, and he is still on the throne of the universe, and the church of God will come off victor in the conflict with the world because the omnipotent God lives in her and one like the Son of Man walks amid the seven golden candlesticks. In the previous chapters we have seen the dragon, and the beast, and the false prophet persecuting the church, but in this chapter we see them completely overthrown, and the divine captain of our salvation leading his followers to victory. It is easy to catch the practical encouragement found in these visions, both as it affected the churches addressed and as it sings down the centuries to every well-fought battlefield of the church's activities.
