Lacking knowledge of God's Word in the Bible can easily be angered by someone who is trying to point out the Word of God in the Bible.Do not be angry if someone else here is reminding you of God's Word and His promises. We are to believe everything that God says or we are making God a liar. If a brother or sister in Christ Jesus will not correct anyone who is sinning and grieving the Holy Spirit because of what they says or write; God will hold that against them judgement time. What did God saied in the Bible? We are to pray in the closet; meaning alone, and then he hears us. We are not to be like hypocrites.

A christian who believe that they don't have demons in them are wrong. Yes, they cannot be possessed but they definitely can be oppressed. This is what you call "indwelling demons" in them. How can you cast out demons from someone who is wallking with God and filled with the Holy Spirit? Are you saying the same thing what the Pharisees said to our Lord Jesus? So, you agreed that Jesus is full of demons? Oh, this is grieving the Holy Spirit.
