This is what Jesus told them: “Take nothing for your trip except a walking stick. Take no bread, no bag, and no money in your pockets. Wear sandals, and take only the clothes you are wearing. When you enter a house, stay there until you leave that place. If any town refuses to accept you or its people refuse to listen to you, then leave that town. Shake its dust off your feet. This will be a warning to them.” (Mark 5: 8-11)So the disciples left behind their architectural guides; pergolas for fêtes on wet days; attendance record books; rules on how to count the congregation; 10-point guides to evangelism; silverware; capos; Powerpoint DVDs; service books; 25 years of Spring Harvest songbooks; little clicky machines for counting attendance; communion rails; Beryl tea services and books of canon law.
But they didn't throw them away.
They reckoned they'd need them later.
