HOW YOU CAN, AND DO, HAVE DEMONS - EVERYONE HAS DEMONS, NO EXCEPTIONS (so this includes all Christians).
When you are Born Again as a Christian/Believer/True Worshiper, JESUS'/Yeshua'/Holy Spirit comes to abide in your SPIRIT. Demons CANNOT get INTO your Spirit.
You are a triune being - BODY, SOUL and SPIRIT. Your SOUL is your MIND, WILL and EMOTIONS.
BODY - Christians can have a sickness/disease just like the UN-saved. That's caused by demons (if not caused by other factors).
SOUL - Do you have a bad temper? That's a demon. Is there mental illness in your family background? That is a demon. Do you have trouble serving God? That's a demon. Do you have problems with bad thoughts? That is a demon(s) in your mind, will or emotions.
Mark 1:39 - And He (Jesus) preached in their synagogues (churches) throughout ALL Galilee and CAST OUT DEMONS. (IN the church? Yes! Is your church casting out demons?) If not, pack your bags and stay home.
IF My people, who are called by My name, shall humble themselves, pray, seek, crave, and require of necessity My face AND turn from their wicked ways, THEN will I hear from Heaven, forgive their sin, and heal their land. II Chronicles 7:14
Are you a Believer? Yes or No! Jesus'/Yeshua' said, Those that Believe SHALL cast out demons (Mark 16:17). Once again Are you a Believer? Yes or No! When you believe this Word from God, then you can have victory in your life. You need to be in your Bible and be building your faith. The God kind of faith comes only from knowing and believing God's Word. Faith comes by hearing [hearing God's Word in your spirit, not with the natural ears, you must read His Word and hear Him speaking to you from His Word].
