Revelation 5:9 –And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;

I admit, sometimes my thoughts are a little odd! Even those who love me will tell you that sometimes my mind goes to weird places …
Wednesday’s are often a highlight in my week, as it’s the day we have our Choir rehearsal. So perhaps it’s natural that my mind turned to the song of the redeemed today. But somehow I think I came from a sideways direction.
“So,” I thought, “I wonder what language they sing in?” Then I thought, “In Heaven. Wonder what style they sing in?”
OK, the language thing is easy. Remember what happened at the first Pentecost? “Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. (Acts 2:6) I think the song of the redeemed can be understood by everyone. But the style thing? After all, there are people “out of every kindred, and tongue, and people, and nation”. That’s a whole lot of different musical and vocal styles!
Come out on a limb with me… I believe (with no biblical foundation) that the song of the redeemed is an expression, an outpouring of pure love — my thoughts about language, and style, are completely irrelevant. Heavenly worship is a bliss-filled outpouring of love and praise.
Of course I’m speculating, wildly, following the trail of a random thought. But I am sure as sure can be that music is a language close to God’s heart. David Jeremiah notes that there are 575 references to praise, music and singing in the Bible.
When God created the Earth, ” … when I laid the foundations of the earth” … “the morning stars sang together, and all the sons of God shouted for joy” (Job 38:4)
When God gave us the Bible, He gave us — among all it’s other treasures — the greatest of songbooks, the Book of Psalms. Much of the songbook was given through the man “close to God’s own heart”, David, the “sweet singer of Zion”.
The end of this is that worship is the main activity of those in Heaven:

Thou, even thou, art Lord alone; thou hast made heaven, the heaven of heavens, with all their host, the earth, and all things that are therein, the seas, and all that is therein, and thou preservest them all; and the host of heaven worshippeth thee. (Nehemiah 9:6)

Now I’ve followed my silly thought to its end … I don’t know what worship in Heaven will be like. It’s indescribable. But I do know that I’m looking forward to it! I cannot imagine any more wonderful thing.
