So what songs last the longest? Why is it we keep singing hymns that were written several centuries ago and they remain fresh to our hearts and minds? The answer, I think, is found in Matthew 24:35 and Luke 21:33. There, the Bible says that heaven and earth will pass away but that the Word of God will never pass away.
If you compose a love song about a girlfriend or boyfriend and then he/she dies or leaves you, I doubt that you would keep singing such a song. You will not want it because it might remind you of something you would not want to remember. If you wrote and sang a song like “Tawala Kenya” which was sang in praise of President Daniel Arap Moi of Kenya, when he leaves office, the song would become irrelevant. People come and go, good and bad. Songs like “I’m not sober” make sense when you are not sober. “My land is Kenya” is only relevant to Kenyans. The world and all in it passes away. Only the Word of God remains forever.
If you write a song about the word of God, cite it, refer to it, apply it, etc, I promise you, your song will be bigger than you. It will be as big as God’s Word and it will be hard to pass away. What is even more important would be if the writer of the song highly respects and esteems this Word of God and lives by it. It will not be mere lip service to it. It will do what God says His Word does, i.e. never returns to Him without accomplishing the purpose for which it was sent out.
