Power is the ability to accomplish one’s mission or objective; the capacity to get things done. While Authority is delegated power, the right to do something, for instance, parents ideally possess the capacity and right to set rules in their homes for their families. A traffic warden may not have the physical ability to stop a car but power has been delegated to him to control traffic so he can stop any size or type of car by just a hand signal. Jesus, while here on earth exercised both authority and power. For example in Luke 4:31-36 (emphasis on vv 32 and 36), while teaching in Capernaum, He cast out an unclean spirit from a man: “But Jesus rebuked him saying, Hold thy peace, and come out of him” (Luke 4:35). The crowd watched in amazement as the demon came out without harming the person. They then exclaimed, “…. What a word is this! For with authority and power he commandeth the unclean spirits, and they came out” (Luke 4:36b).

So also, the Holy Spirit possesses all power and authority and has empowered the believer as illustrated/seen in (Acts 2:1-4) on the day of Pentecost. As a result of that experience of Pentecost, a lame man walked when Peter prayed (Acts 3:7), the sick were healed when Peter’s shadow touched them (Acts 5:15), Peter and the rest received boldness (Acts 2:14), souls were saved (Acts 2:36-37) and so many other powerful deeds were done.
