Music is a deep and fundamental part of our human nature. We remember songs and music with remarkable clarity, even from early childhood. Music informs, inspires and alters our feelings. Songs bring together our emotions and our intellects, our hearts and our minds.
For all these reasons, songs have played an important part in human religion throughout the ages. Moses composed a song as he was crossing the parted waters of the Reed (not Red!) Sea. King David was an accomplished musician and songwriter. Isaiah delivered his prophesies as songs. Jesus does not seem to have used music much in his ministry, but St Paul was a keen singer, and may have composed some songs. In his letter to the Christians in Ephesus, Paul urged them to use of music in their meetings.
Singing together - be it in a church or a football stadium - unites and energises people. It is also an excellent way to learn important things. So, in our Christian worship, singing together is a valuable activity in itself.
Finally, because music is so powerful, we would do well to choose carefully the music that we play at home, in the car, or on the bus. Good music, with good words will feed our souls. Bad music with careless words can do the opposite.
