A double-minded man Ανηρ διψυχος, a man who has, as it were, two souls; whose heart is divided between God and the world, and is not simply given up to him, nor entirely confides in him for the direction, aid, and support which he stands in need of; is unstable in all his ways Being without the true wisdom, he perpetually disagrees both with himself and others; and will be perpetually running into inconsistencies of conduct, while those imperfect impressions of religion which he feels will serve rather to perplex and torment than to guide and confirm him in the right way.
