19-23. Confirming Ga 5:18, by showing the contrariety between the works of the flesh and the fruit of the Spirit.
      manifest--The hidden fleshly principle betrays itself palpably by its works, so that these are not hard to discover, and leave no doubt that they come not from the Spirit.
      which are these--Greek, "such as," for instance.
      Adultery--omitted in the oldest manuscripts.
      lasciviousness--rather, "wantonness" petulance, capricious insolence; it may display itself in "lasciviousness," but not necessarily or constantly so (Mr 7:21, 22, where it is not associated with fleshly lusts) [TRENCH]. "Works" (in the plural) are attributed to the "flesh," because they are divided, and often at variance with one another, and even when taken each one by itself, betray their fleshly origin. But the "fruit of the Spirit" (Ga 5:23) is singular, because, however manifold the results, they form one harmonious whole. The results of the flesh are not dignified by the name "fruit"; they are but works (Eph 5:9, 11). He enumerates those fleshly "works" (committed against our neighbor, against God, and against ourselves) to which the Galatians were most prone (the Celts have always been prone to disputations and internal strifes): and those manifestations of the fruit of the Spirit most needed by them (Ga 5:13, 15). This passage shows that "the flesh" does not mean merely sensuality, as opposed to spirituality: for "divisions" in the catalogue here do not flow from sensuality. The identification of "the natural (Greek, 'animal-souled') man," with the "carnal" or fleshly man (1Co 2:14), shows that "the flesh" expresses human nature as estranged from God. TRENCH observes, as a proof of our fallen state, how much richer is every vocabulary in words for sins, than in those for graces. Paul enumerates seventeen "works of the flesh," only nine manifestations of "the fruit of the Spirit" (compare Eph 4:31).
