Can a Christian Have a Demon?
Short answer. Yes and no. A Christian cannot be demonically possessed, but a Christian can absolutely be demonically oppressed. They are different. Possession deals with ownership. Christians belong to the Holy Spirit, not any demon. On the other hand, our souls, even our health can absolutely be tormented and affected by demons. How do we know this?
“Then should not this woman, a daughter of Abraham, whom Satan has kept bound for eighteen long years, be set free on the Sabbath day from what bound her?” Luke 13:16
If she is a daughter of Abraham, then she is obviously of the household of faith, which means, believers can also be demonically bound.
I myself have been oppressed by spirits of fear, rage and more. But God is faithful! Sometimes a person experiences complete deliverance in an area, sometimes it is a process, layer by layer. Let us continue to put our hope and confidence in Him who loves us.
