Verse 8.— He that committeth sin is of the devil. Since sin emanates from the devil, and is, therefore, of him, those who work sin, who exhibit a sinful life, give, thereby, all the proof sound reason can demand that they are under the dominion and control of the devil. From the very beginning of the world the devil sinned. For this purpose the Son of God was manifested. That he might destroy sin and its punishment, which are the works of the devil, is the purpose for which the Son of God came into the world and appeared among men in the flesh. Dr. Macknight says: "Demolish that horrible fabric of sin and misery which the devil, with such art and industry and malice, hath reared in our world. From this text some have argued that all moral and penal evil will, at length, be extirpated from the universe."
