Acts 5:12 And through the hands of the apostles many signs and wonders were done among the people. And they were all with one accord in Solomon’s Porch. The fact that there is no deliverance in a ministry it does not mean the absence of demons. It simply means you gladly fellowship with them. Mark 16:17 And these signs will follow those who believe: In My name they will cast out demons.
When Jesus sent His disciples, they had 3 tasks. Deliverance, Healing and to teach the Gospel. If Jesus acknowledges that there is a need for the three ministries and you are called but denounce one of them, who are you following. Luke 9:1-2 Then He called His twelve disciples together and gave them power and authority over all demons, and to cure diseases. He sent them to preach the kingdom of God and to heal the sick.
Nicodemus said only one who God is with, can perform signs and wonders. The Holy Spirit cannot dwell in a place and be idle and demons cannot sit comfortably in His presence. John 3:2 This man came to Jesus by night and said to Him, “Rabbi, we know that You are a teacher come from God; for no one can do these signs that You do unless God is with him.”
You have been given authority, use it to help God’s people.
