Acts 28:8 NKJV
And it happened that the father of Publius lay sick of a fever and dysentery. Paul went in to him and prayed, and he laid his hands on him and healed him.
This is the only specific reference, except for Jesus, where a person is credited with the healing. We know it is the Jesus in us that is doing the healing. It is by the authority and power of the Holy Spirit. We do not want to come across as being the source of the miraculous, but we are the ones laying on hands.
Dont leave it there. It is our hands and our words as we use His authority to cast out the infirmity, but it is only because of God's grace. Because of Grace we have been given the Holy Spirit to live in us. It is that spirit that comes upon us and does the healing. But in their eyes we did it. I am careful to make sure they know that Jesus is the source, not me. I was just the vessel that was used.
Jesus did say that we would do everything He did and even greater things. (John 14:12) He healed the sick. He even raised the dead. If He did it, we too can do it. Jesus was also a man who had the Holy Spirit and now we also have the same Spirit that raised the dead living in us. So we shall lay hands on the sick and heal them. (Mark 16.18)
