A double-minded man is unstable— "He, whose schemes are divided between God and the world, and who cannot cheerfully and resolutely commit himself, in confidence of divine support, to be led whithersoever Providence shall please, is unsettled in all his ways: he will perpetually be running into inconsistencies of conduct; and these imperfect and undetermined impressions of religion which he feels, will serve rather to perplex and torment, than to guide and secure him." Moreover, he who desires the end, must desire, or at least fully acquiesce in, the necessary means; else he is double-minded. He would, and he would not.
