The fruits of the Holy Spirit are love, joy, peace, goodness, long-suffering, kindness, faith, gentleness, self-control (cf. Galatians 5:22-23). The fruits of the spirit of evil are hatred, worldly despondency, restlessness of soul, a troubled heart, guile, inquisitiveness, negligence, anger, lack of faith, envy, gluttony, drunkenness, abusiveness, censoriousness, the lust of the eyes (cf. 1 John 2:16), vanity and pretentiousness of soul. By these fruits you may know the tree (cf. Matthew 12:33), and in this way you will certainly recognize what kind of spirit you have to deal with. An even clearer indication of these things is given by the Lord Himself when He says, ‘A good man out of the good treasury of his heart brings forth good things; and an evil man out of the evil treasury of his heart brings forth evil things’ (Matthew 12:35). For as the tree, so is the fruit.
