And the women answered one another as they played, and said, Saul hath slain his thousands, and David his ten thousands. And Saul was very wroth, and the saying displeased him; and he said, They have ascribed unto David ten thousands, and to me they have ascribed but thousands: and what can he have more but the kingdom? And Saul eyed [literally meaning that he looked with jealousy upon] David from that day and forward. And it came to pass on the morrow [the next day], that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul’s hand. And Saul cast the javelin; for he said, I will smite David even to the wall with it. And David avoided out of his presence twice.
1 Samuel 18:7-11
I was reading my Bible today, when this passage really stood out to me. First, we see the women praising David for slaying his ten thousands, but Saul for slaying his thousands. This rejection made Saul angry with David, and jealous of him. The very next day, an evil spirit came upon Saul and caused him to become exceedingly angry, to the point of attempting to murder David!
The same thing happens today. A person can experience rejection, which leads them to other emotions such as rebellion, jealousy, anger, and so forth. As a result, they can make themselves available to unclean spirits, which will take advantage of these sins of the heart and take up residence.
That is why our reactions to what is done to us is so important to subject to the obedience of Christ. Whether it be rejection, theft, abuse, molestation, etc., which is done to us, our reaction to it is what opens the door to the enemy. Rejection can come from our parents, siblings, friends, family, teachers, peers, or even ourselves (self-rejection).
Many times, when dealing with cases of jealousy, anger, hate, rebellion, and so forth, the root is often rejection. Rejection is one of the biggest, and well known roots in the ministry of deliverance!
