Praying

I read in a book lately about praying his room. That is, going into his room and reading scripture and praying away the demons and bad habits. They even suggested playing Gospel music in his room when he is out, but I didn't go that far. Not yet anyway.
So last night I went into his room, opened his window, and prayed over his bed, his computer, his phone, his TV and his room in general. I prayed that the demons in his life would be renounced and the spirit would convict him and give him peace and a purpose.
I then prayed, for myself, that he would come home safe and soon.
About ten minutes later, he walked in the door. AND was polite to me and told me he loved me.
I'm going to make this a habit.
