King Saul was often tormented by evil spirits. When this happened, he called for David, the Psalmist and shepherd boy, to play the harp. The evil spirits always departed.
Praise and worship are dreaded weapons in Hell. Demon powers are demoralized by it. Don’t neglect this weapon. It is too powerful to ignore. As you lift your hands in worship and praise, you will literally purge the atmosphere of demonic activity.
“And it came to pass, when the evil spirit from God was upon Saul, that David took an harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.”
(1 Samuel 16:23)
