Since when did rocks cry out? Where on earth did this idea even come from? Straight from the Bible, that’s where. This piece is in the tradition of a true spiritual but has a known author, Hall Johnson. The idea of rocks crying out comes from the story of Christ’s triumphal entry into Jerusalem the week before the Crucifixion. Christian churches celebrate this event on Palm Sunday, one week before Easter. Christ comes riding into the city on a donkey, people gather around, throw their cloaks on the ground before Him, and wave palm branches.
