Mumford and Sons have become one of the most popular and influential bands in the world today. In terms of live shows, besides U2, they are regarded as probably the best live band around. Something that makes them unique is the wide variety of people their music attracts. From young hipsters to old lovers of classic rock, to post-modern relativists to atheists to reformed Christians. Their music is excellent and it appeals to many. It is an amazing thing and it brings me joy to hear a band like Mumford and Sons singing Amazing Grace and Come Thou Fount, praising God in the midst of their audience. It is wonderful that God uses common ground among people, such as music, in order to make His name known. I don't even know if Mumford and Sons are Christians, but based on their music, I think they are. Either way, God's beautiful grace is being declared among people who would otherwise never step in a church. That excites me.
