The devil is an enemy to God

1. Mosiah 16: 5
     5 But remember that he that persists in his own carnal nature, and goes on in the ways of sin and rebellion against God, remaineth in his fallen state and the devil hath all power over him. Therefore he is as though there was no redemption made, being an enemy to God; and also is the devil an enemy to God.
2. Moro. 7: 12
     12 Wherefore, all things which are good cometh of God; and that which is evil cometh of the devil; for the devil is an enemy unto God, and fighteth against him continually, and inviteth and enticeth to sin, and to do that which is evil continually.
