To a man who lives unto God, nothing is secular, everything is sacred. He puts on his workday garment and it is a vestment to him. He sits down to his meal and it is a sacrament. He goes forth to his labor, and therein exercises the office of the priesthood. His breath is incense and his life a sacrifice. He sleeps on the bosom of God, and lives and moves in the divine presence. To draw a hard and fast line and say, “This is sacred and this is secular,” is to my mind, diametrically opposed to the teaching of Christ and the spirit of the gospel.
The Lord hath cleansed your houses, he has cleansed your bed chambers, your tables…He has made the common pots and pans of your kitchens to be as the bowls before the altar— if you know what you are and live according to your high calling. You housemaids, you cooks, you nurses, you ploughmen, you housewives, you traders, you sailors, your labor is holy if you serve the Lord Christ in it, by living unto Him as you ought to love. The sacred has absorbed the secular.
—Charles H. Spurgeon, Sermon: “All for Jesus” (1874).
