Those who focus only on the drabness of the supermarket, or on the onions or the diapers themselves, haven't an inkling of the mystery that is at stake here, the mystery revealed in the birth of that Baby and consummated on the Cross: my life for yours.
The routines of housework and of mothering may be seen as a kind of death, and it is appropriate that they should be, for they offer the chance, day after day, to lay down one's life for others. Then they are no longer routines. By being done with love and offered up to God with praise, they are thereby hallowed as the vessels of the tabernacle were hallowed--not because they were different from other vessels in quality or function, but because they were offered to God. A mother's part in sustaining the life of her children and making it pleasant and comfortable is no triviality. It calls for self-sacrifice and humility, but it is the route, as was the humiliation of Jesus, to glory.
