The work of a Beethoven, and the work of a charwoman [cleaning lady], become spiritual on precisely the same condition, that of being offered to God, of being done humbly "as to the Lord." This does not, of course, mean that it is for anyone a mere toss up whether he should sweep rooms or compose symphonies. A mole must dig to the glory of God and a cock must crow. - C.S. Lewis, The Weight of Glory.
