One Saturday when I was on my way to church I happened to hear a song on the stereo of the people who give me my weekly ride to church. I asked the driver about the origin of said song, and he told me that it got its start as a spiritual.
I thought about it again yesterday as my friend, born in Nigeria, brought me to church. I thought some more later as I took a walk. I then came to this simple conclusion, that those songs have had impact. Not just in the time period of their creation, but now.
God Bless and keep all of you out there.
