"As soon as the sower goes forth to sow his seed, the fowls of the air go forth also. The more good is being done in any place, the more surely Satan oppose it. You cannot destroy a wasp's nest without being attacked in return. Yet this is better than stagnation. In a slumbering church it is the adversaries chief business to rock the cradle, hush all noise, and drive away even a fly which might light upon the sleeper's face; Satan's greatest dread is lest the church should be aroused from her dreamy slumbers."
