God has called us to the kind of supernatural life that Jesus lived. At the beginning of the New Testament church, God confirmed His Word with signs following, and the presence and words of angels further established the gospel in the Earth.
The book of Acts is replete with angelic visitations. A case in point would be the incident involving Peter in Acts 12. The believers who were gathered for prayer were skeptical about Peter's being released from prison, choosing to believe that his angel rather than Peter was at the door.
