Who can cast out demons?
Every child of God (believer in Christ Jesus) has the authority necessary to drive out demon spirits:
Mark 16:17, “And these signs shall follow them that believe; In my name shall they cast out devils…”
We are given authority over all powers of the enemy, but we need to exercise our authority through faith.
Anybody who is a child of God is quite capable of casting out evil spirits, however, it is always helpful to understand this type of ministry, as there are often more factors involved that may not be solved by simply casting out a demon. Many times there are strongholds, legal grounds and groupings of demons that need to be addressed. Therefore, the more you know and understand about this type of ministry, the more effectively you will be able to minister to those in bondage.
