To be without zeal is to be without the zest of living. Zeal and enthusiasm incite to glorious achievement in every aim and ideal that the mind conceives. Zeal is the impulse to go forward, the urge behind all things. Without zeal stagnation, inertia, death would prevail throughout the universe. The man without zeal is like an engine without steam or an electric motor without a current.
Energy is zeal in motion, and energy is the forerunner of every effect.
If you desire a thing, you set in motion the machinery of the universe to gain possession of it, but you must be zealous in the pursuit in order to attain the object of your desire. Desire goes before every act of your life, hence it is good. So the universal desire for achievement, giving its mighty impulse to all things, is divinely good. Divine enthusiasm is no respecter of persons or things. It makes no distinctions.
