It can hardly be doubted that the _glassy sea_ spoken of in these words is the same as that already met with at chap. iv. 6. Yet again, as in the case of the hundred and forty and four thousand of chap. xiv. 1, the definite article is wanting; and, in all probability, for the same reason. The aspect in which the object is viewed, though not the object itself, is different. The glassy sea is here _mingled with fire_, a point of which no mention was made in chap. iv. The difference may be explained if we remember that the "fire" spoken of can only be that of the judgments by which the Almighty vindicates His cause, or of the trials by which He purifies His people. As these, therefore, now stand upon the sea, delivered from every adversary, we are reminded of the troubles which by Divine grace they have been enabled to surmount. It was otherwise in chap. iv. No persons were there connected with the sea, and it stretched away, clear as crystal, before Him all whose dealings with His people are "right." The sea itself is in both cases the same, but in the latter it is beheld from the Divine point of view, in the former from the human. The vision as a whole takes us back to the exodus of Israel from Egypt, and hence the mention of _the song of Moses, the servant of God_. The enemies of the Church have their type in Pharaoh and his host as they pursue Israel across the sands which had been laid bare for the passage of the chosen people; the waters, driven back for a time, return to their ancient bed; the hostile force, with its chariots and its chosen captains, "goes down into the depths like a stone;" and Israel raises its song of victory, "I will sing unto the Lord, for He hath triumphed gloriously, the horse and his rider hath He thrown into the sea."[418] The song now sung, however, is not that of Moses only, the great centre of the Old Testament Dispensation; it is also _the Song of the Lamb_, the centre and the sum of the New Testament. Both Dispensations are in the Seer's thoughts, and in the number of those who sing are included the saints of each, the members of the one Universal Church. No disciple of Jesus either before or after His first coming is omitted. Every one is there from whose hands the bonds of the world have fallen off, and who has cast in his lot with the followers of the Lamb. Hence also the song is wider in its range than that by which the thought of it appears to have been suggested. It celebrates the _great and marvellous works_ of the Almighty in general. It speaks of Him as the _King of the nations_, that is, as the King who subdues the nations under Him. It rejoices in the fact that His _righteous acts have been made manifest_. And it anticipates the time when _all the nations shall come and worship before_ Him, shall bow themselves at His feet, and shall acknowledge that His judgments against sin are not only just in themselves, but are allowed to be so by the very persons on whom they fall.
