An illness , disease, infirmity, or other physical, mental or spiritual abnormality is revealed. 

The Holy Spirit reveals what Jesus would have the born-again Spirit filled Christian to say or pray regarding a healing need(John 16:13-15). Anyone or several of the gifts of the Holy Spirit may be given in order to minister to a person. The signs of power  are to confirm the gospel (Mark 16:20), and to bless people with wholeness.
