Well I was joining in last night with some friends singing in Shona and Ndebele, and I havent a clue what I was singing about (though some of it was about Jesus). Well,I was thoroughly enjoying the experience, and not feeling remotely hypocritical or dishonest. I dint know what it meant, but I would hazard a guess if I had known i would not have "believed" it. But I certainly believe in the validity of singing along with my friends.
