Duty performed gives clearness and firmness to faith, and faith thus strengthened through duty becomes the more assured and satisfying to the soul.

One of the great lessons the fall of the leaf teaches, is this: do your work well and then be ready to depart when God shall call.

~ Tryon Edwards

Science has sometimes been said to be opposed to faith, and inconsistent with it. But all science, in fact, rests on a basis of faith, for it assumes the permanence and uniformity of natural laws - a thing which can never be demonstrated.

~ Tryon Edwards

Any act often repeated soon forms a habit; and habit allowed, steady gains in strength, At first it may be but as a spider's web, easily broken through, but if not resisted it soon binds us with chains of steel.
