It is a very terrible thing to let conscience begin to grow hard, for it soon chills into northern iron and steel. It is like the freezing of a pond. The first film of ice is scarcely perceptible; keep the water stirring and you will prevent the frost from hardening it; but once let it film over and remain quiet, the glaze thickens over the surface, and it thickens still, and at last is so firm that a wagon might be drawn over the solid ice.
So with conscience, it films over gradually, until at last it becomes hard and unfeeling, and is not crushed even with ponderous loads of iniquity.— SPURGEON.
