With Fear and Trembling, in Singleness of Heart

So far from that, that it binds the Obligations to Duty more strongly upon us; for the Gospel Institution most strictly enjoins Obedience; it requires all not to be slothful in Business, and commands Servants to be obedient to them that are their Masters, according to the Flesh, with Fear and Trembling, in Singleness of Heart.
~ Stephen Hales (1734)
