When we travel, we make a mental list of all the things we will need: our toothbrush, pajamas, passport, iPad, breviary, jacket—the list goes on and on. But Jesus seems more worried about the disciples taking too much rather than forgetting something important. What is the deal here? Why does Jesus insist on this radical austerity? He is teaching them, and us, to trust. He wants the disciples to be uncluttered and even a little insecure, so that they will rely more on God’s providence than on the contents of their backpacks. We never really learn how much God cares for us until we let go of the many securities that sustain us in our lives.
—from The Way of Serenity by Fr. Jonathan Morris, Ch. 7: We Have Everything We Need
