"And they sang a new song, saying, 'Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, . . .'" (Rev. 5:9)
A comment about what directly precedes the singing of the new song in worship in the previous v. 8. It talks about golden bowls full of incense which are the prayers of the saints. Oh my goodness, hallelujah! Again, prayer and the new song tied together! Again, prayer and praise always go together. And just think, our prayers are collected and held in heaven for worship of the Lamb.
The original Greek word - "adousin" is present tense - "they are singing". It is a historical present describing an event which has already transpired. This is their continuous blessed occupation. Both the living creatures and elders sing this new song. I believe when the church is engaged in high praise that we are literally joining the hosts of heaven in singing the new song! It is the chorus of the redeemed! The great victory in suffering and death by the Lamb inspires this new song. The suffering Servant has died, and broken the bond of the oppressor claiming by right of purchase you and me as His own; and the price was His blood.
Here in this passage again, we see that this is for every tribe (smaller divisions of peoples), larger groups denoted by different languages where every man can learn of the wonderful works of God in their own tongue. Goes on to mention people and nations, even larger groups. It simply is saying that this new song is a global thing meant for all kinds of peoples. The global extent of the gospel is expressed here. All who have been redeemed from the earth are joining in singing the new song!
The new aspect of the song here is worship motivated by the impending opening of the scroll and the words of this song record the beginning by the Lamb of the events which would quickly lead to the climax of history and the establishment of His Kingdom.
How important is the singing of the "new song" to our Lord? mjm
