He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, that he might destroy the works of the devil.

 (iv) He tells us whence sin comes. It comes from the devil; and the devil is he who sins, as it were, on principle. That probably is the meaning of the phrase from the beginning ( 1 John 3:8). We sin for the pleasure that we think it will bring to us; the devil sins as a matter of principle. The New Testament does not try to explain the devil and his origin; but it is quite convinced--and it is a fact of universal experience that in the world there is a power hostile to God; and to sin is to obey that power instead of God.
