Law's first rule for life:
To fix it deeply in my mind that I have but one business upon my hands, to seek for eternal happiness by doing the will of God.
--quoted in W. Barclay, The Letters of James and Peter, 96
Happiness through obedience. Not dutiful, stoic obedience. Not happiness via disobedience. But happiness through obedience. The only true obedience, the only true happiness.
