In Mark 6:8-10, Jesus gave some interesting instructions to his disciples on what they were to take with them and where they were to stay as they journeyed out on their first missionary venture. It seems a bit detailed to us. But it was truly purposeful: He wanted them to see that the urgency of the mission required an approach that kept things simple, unencumbered. “He charged them to take nothing for their journey except a staff—no bread, no bag, no money in their belts—but to wear sandals and not put on two tunics. And he said to them, ‘Whenever you enter a house, stay there until you depart from there.’”
There are some striking echoes in this to the Exodus. At that time, God’s people were being set free from slavery in Egypt. Now here were these men, being sent out on a mission to point God’s people to freedom from slavery to sin. Urgency drives simplicity!
