Are you struggling with anxiety, worry or fear? Are you struggling with thoughts that appear not to be your own?
If so, you may be demonized. Being demonized does not mean a demon possesses you. A demon can not own a true believer. There may be areas in your personality that the Holy Spirit may not control.
So what do you do?
First, Submit to God and resist the enemy (James 4:7);
Second, Ask the Lord to give you a clean heart (Psalm 51:10-12);
Third, Ask the Lord to search you and show you any areas that are not of the Lord (Psalm 139:23-24);
Fourth, Renew your mind (Romans 12:2). Think and meditate on good things, and keep your mind on Christ (Isaiah 26:3). God promises us we will have peace if we do this; and,
Fifth, Put on the whole armor of God every day (Ephesians 6).
