In the Lord’s Prayer we are told to pray for our daily bread (Matt 6:11). This prayer is a model of what it means to trust and ask God to meet our needs, our physical and spiritual needs, by asking God to provide our most basic need, the need to eat. But how does God normally give us our daily bread? None of us got up this morning, went outside, and collected the daily bread that God deposited on our doorstep while we were sleeping. We either went to the refrigerator or drove somewhere to get breakfast. We did this because God provides our daily bread through other people, such as farmers, bakers, truck drivers, grocery store owners, and everyone else who is involved in getting us our meals. Though God could, if he so chose, give us our food directly and miraculously (as he did for Israel when he fed them with manna and quail), he normally provides us our food through other human beings, who serve each other according to their unique opportunities and abilities. This is the doctrine of vocation, or what God does in giving each human being unique callings in this world.
