Rev.14:3 – And they sang a new song before the throne and before the four living creatures and the elders; and no one was able to learn the song except the 144,000 who had been purchased from the earth.
Our lives have changed more than we know since we were born again. One of the sure indications of this change is the songs that flow out of our heart. Jesus said that we speak out of the abundance or overflow of our hearts. You can tell an awful lot about someone by the songs that they sing.
David was a great example of this; he often spoke about singing a new song. What David meant by this was singing spontaneously out of the overflow of his heart. His new songs were permeated with thanksgiving. He would sing, “Give thanks to the Lord for He is good, His mercy endures forever” again and again. Thanksgiving is also the theme of our new song today. The Lord has done great things for us, Thanksgiving is a great time to sing those new songs. Here is an excerpt from Jonathan Edwards Thanksgiving message from 1740 on singing this new song.
“The melody of the heart with which they sing is new. Before they knew but how to sing praise to God: they were unlearned; they could make no melody in God’s ear; they had no skill in divine music; they had not learned the tune, nor could they sound one harmonious note. Their hearts were like an instrument that is unstrung and broken, wholly out of tune. The notes were most jarring and discordant. If they pretended to sing praise to God, it was howling and not singing in God’s ears. But now God has put their hearts in tune. Now there is some inward harmony. Now there is divine harmony that is melodious unto God. Thus the song that the saints sing is new with respect to what went before, as ’tis later, and as it succeeds and is introduced on the decay and removal of it.”
We were all singing different songs, worldly songs, before our hearts were made new. You can’t really make rules about what are appropriate songs to sing, our hearts can only sing about the things that we love. Once your heart begins to be in tune with Christ’s work of redemption and renewal you too will be singing this brand new song.
