Inspired by the conflict in Northern Ireland, U2 released one of their iconic recordings - Sunday Bloody Sunday - in 1983. The song lyrically poses a question common to the writers of the Scriptures, "How long, how long must we sing this song?" While spending this week walking in some of the poorest places on earth - dry, hot and broken places - I found myself asking the same question: how long Lord, how much longer must we sing this same song? This week as we kick off our new series, "David & Bono | When the Word Sings," we'll take an honest look at the pain in the world, and try to figure out together how to sing a new song.
