Praises

Lower down in the chapter, the countless multitude of angels celebrates His praise, but the angels are lower down in another sense too. An angel cannot speak of Him as the One "who loved me, and gave Himself for me." They praise Him for what He is to the saints. As the servants at the welcome of the prodigal son, they praise the master for what they learn him to be as a father, in his welcome of his long-lost son. But this does not change their position; they are still the servants.
Then John hears every creature in heaven, and in earth, and under the earth, taking up the praise. This is anticipative, but it was given to John to know it beforehand for the comfort of his and our hearts. Peter had been with the Lord in the holy mountain, and had seen the power and coming of our Lord Jesus Christ. But in point of fact that day is future. And so it is with John. It is the grand result before his eyes, as a sample and pledge of what it will be when the blessed One shall have risen up from His Father's throne to banish the adversary from the universe. No place will be left for Satan in the scene God had created for His glory.
What grace of our God to show us this glorious future! This is the time when all the mind in heaven and earth shall be one in worshipping Him who sits upon the throne, and in adoring the Lamb.
