1 Samuel 16:23—And it came to pass, when the evil spirit from God was upon Saul, that David took a harp, and played with his hand: so Saul was refreshed and was well, and the evil spirit departed from him.
The Spirit of God departed from Saul and an evil spirit was sent by God to trouble him. Evil spirits are always waiting to trouble us, but they need permission to attack those who belong to God. A spirit was given permission to oppress Saul. It would put him in a foul mood. Saul invited this spirit through his disobedience and pride. Nevertheless, he did not like the effect the spirit had upon him. Someone in his court suggested that music would cause the spirit to leave him. David was called in to play the harp. The man who has been anointed the next king was called to help Saul deal with the consequences of his choices. It worked. Music seemed to bring the king relief. It works for us too. You’ll find that when you are in a foul mood if you will listen to praise music, you will be uplifted, and your mind will pull out of the rut it seems to be stuck in. If by faith, you can sing, you’ll feel much better. I have even made up songs to deal with certain attacks of the enemy. God allows this to strengthen and test us or wake us up to our sin. In many cities, you can turn on Christian radio and get instant help through the songs of praise. Why was David’s music so effective? The Spirit of the LORD had come upon David in power. (1 Samuel 16:13) A worshipping saint causes the enemy to cringe and flee. There are many stories of the wonders that praise music has done in asylums. It is a powerful tool. Use it for the glory of God.
