It goes something like this: When we pray the Lord's Prayer, we ask God to give us this day our daily bread. And he does. The way he gives us our daily bread is through the vocations of farmers, millers, and bakers. We might add truck drivers, factory workers, bankers, warehouse attendants, and the lady at the checkout counter. Virtually every step of our whole economic system contributes to that piece of toast you had for breakfast. And when you thanked God for the food that he provided, you were right to do so.
God could have chosen to create new human beings to populate the earth out of the dust, as he did with the first man. But instead, he chose to create new life-which, however commonplace, is no less miraculous-by means of mothers and fathers, wives and husbands, the vocations of the family.
God protects us through the vocations of earthly government, as detailed in Romans 13. He gives his gifts of healing usually not through out-and-out miracles (though he can) but by means of the medical vocations. He proclaims his word by means of human pastors. He teaches by means of teachers. He creates works of beauty and meaning by means of human artists, whom he has given particular talents. . . .
. . . . God is milking the cows through the vocation of the milkmaid, said Luther. According to Luther, vocation is a "mask of God." He is hidden in vocation. We see the milkmaid, or the farmer, or the doctor or pastor or artist. But, looming behind this human mask, God is genuinely present and active in what they do for us . . .
. . . . For a Christian, conscious of vocation as the mask of God, all of life, even the most mundane facets of our existence, become occasions to glorify God. Whenever someone does something for you-brings your meal at a restaurant, cleans up after you, builds your house, preaches a sermon-be grateful for the human beings whom God is using to bless you and praise him for his unmerited gifts. Do you savor your food? Glorify God for the hands that prepared it. Are you moved by a work of art-a piece of music, a novel, a movie? Glorify God who has given such artistic gifts to human beings.
Of course, that vocation is a mask of God means that God also works through you, in your various callings. That God is hidden in what we do is often obscured by our own sinful and selfish motivations. But that does not prevent God from acting.
