Evil is a moral rebellion against God. It is contrary to the will of God. There is natural evil (floods, storms, famines, etc.,) and moral evil (adultery, murder, idolatry, etc.). Natural evil is a result of moral evil. Adam’s sin resulted in sin entering the world allowing floods, storms, famines, etc. Evil originated with Satan (Isaiah 14:12-15) and is carried on by man (Matt. 15:18-19). (See Theodicy).
