Hugh Binning, Works, p. 104:
Of creatures we must inquire a quare after a quid; a why, after we know what their will is. But Christians should have their wills so subdued unto God’s, that though no profit nor advantage were to redound by obedience, though it were in things repugnant and cross to our inclination and humour, yet we should serve and obey him as a testimony of our homage and subjection to him. And till we learn this, and be more abstracted from our own interests in the ways of obedience, even from the interests of peace, and comfort, and liberty, we do not obey him because he commands, but for our own sakes.
