The heavenly choir “were singing a new song before the throne and before the four living creatures and the elders. No one was able to learn the song except the one hundred and forty-four thousand who had been redeemed from the earth.” [Revelation 14]

Julie Andrews’ song echoes in our heads: “The hills are alive with the sound of music.” One day it will not the hills but Mount Zion of God will be alive with the sound of music. The choir of the 144,000 sealed by God will be heard singing a new song before the throne. They will be accompanied by the harpists playing their harps reminiscent of the dedication of the wall of Jerusalem in the time of Nehemiah. That choir celebrated joyfully with songs of thanksgiving and songs accompanied by cymbals, harps, and lyres. [Neh 12] The difference being that this song is sung by those purchased and preserved. They are the professing choir of virgins redeemed from the earth and are now rewarded for their faithfulness and purity. They had heard the Lamb say “follow Me” and they did.
The Shepherds of old heard the choir of heavenly angels as they sang “Glory to God in the highest, and on earth peace among people with whom he is pleased” as they proclaimed the Messiah’s birth. What song will you sing for the Messiah king?
