Quickness of moral perception depends on the maintenance of a Nazarite separation from all and everything that might cloud our souls. Take the sons of Aaron for example. They were commanded not to drink wine or strong drink when they went into the tabernacle of the congregation lest they should die, and that they might put difference between holy and unholy, and between unclean and clean, etc. (Leviticus 10) This is an abiding principle; and hence when a believer forgets his heavenly calling, and yields to the indulgence of earthly joys, is “drunk with wine” instead of being “filled with the Spirit,” it is impossible for him to discern between things that differ, or to perceive what is suitable, morally suitable, to God. No greater mistake can thus be made than to expect a right judgment upon moral questions from worldly Christians. They may be perfectly sincere and upright, and may at the same time desire to see the truth, but they have lost their spiritual discernment; and where this is the case truth will soon fail, and he that departeth from evil will be accounted mad.
