Hey there! I’m sorry you’re going through this- it’s no fun! We’ve been there too.
Have you ever read “The Power of a Praying Parent” by Stormi O’Martian? She has a chapter in there all about praying through your home.
One thing we did was teach our daughter Psalm 4:8 “I will both lie down and sleep in peace for you, alone, O Lord, make me dwell in safety.” She recites it to herself when she’s having a hard time.
Also, has your child make a confession of faith (been saved)? If not, this may be a good time to explain again how when we have salvation, we have the power of the Holy Spirit and that He enables us to put on the full armor of God (read that whole thing to him). I know that when I was 8, those thoughts were keeping me awake, and that’s when my dad helped me see that I needed a redeemer, and is when I prayed the prayer of salvation. It didn’t change all at once, like others have said. But when we know the tools to use, and are empowered to use them (by the Holy Spirit), life changes :o)
Blessings to you, and keep up the good fight. You’re doing well, just keep after it.
“Father in Heaven, guard this family as they work through this difficult time together. Allow Dad to take authority in his home. Allow Mom to follow his lead, and show this precious child the order and authority you give to your children over Satan. I pray, right now, that you would send your angels to minister to this family. I pray that you would guard each window, each door, and that your presence would be so overwhelming in their home that darkness will be pushed out. Give this little boy peace and rest. Help him identify anything in his surroundings that might be contributing fuel to this attack, and help him remove it. We know you are with us no matter what, and that you, the Good Shepherd, guard your sheep. Thank you for mercy and grace. Thank you for the promise of rest for the weary. In the name of your son, Jesus, Amen.”
