There are always two spirits at work: the Holy Ghost and a satanic or false spirit. Witchcraft comes from a satanic spirit and opposes God's Spirit.
The Bible likens jealousy to a weapon. Lives are spared when this weapon rests in the bosom of someone with righteous motives. Yet, when the foolish wield this weapon, jealousy leads to destructive outcomes. The very thing that the Lord possesses to protect His people, His land, and His name, can push the ungodly men into an uncontrollable rage. God’s jealousy protects the righteous and consumes the guilty. Yet, the jealousy of an unrighteous man has consumed the lives of many innocent people. The Bible states that “jealousy is cruel as the grave: the coals thereof are coals of fire, which hath a most vehement flame” (Song of Solomon 8:6). Misplaced jealousy is a most dangerous weapon.
The Bible seems to point to Pharaoh most often as an example of someone with a heart hardened through sin and the deceitfulness of power and fame. Pharaoh's hardened heart led him from one rebellious act to the next. He constantly fought against the Lord and the Lord’s man. Even after all of the miracles in Egypt and the abundance of judgments, he chose to pursue the children of Israel as they departed from Egypt. Pharaoh's hardened heart led him to pursue them to the Red Sea. Out of all the troublesome effects of a hard heart, the most troubling aspect is that it refuses to hearken to the words of the Lord. On at least five occasions, the Lord makes this connection (Exodus 7:13, 22; Exodus 8:15, 19; Exodus 9:12). A hard heart closes the ears to the truth and sets the individual up for greater judgment.
