"And now I am sending upon you what the Father has promised. Stay in the city, until you are clothed with the power from on high." (Luke 24: 49)
The Holy Spirit is the greatest promise of God to man. He is the power from on high. There is a power from on high and a power from below.
Power is the dominant attribute of the Holy Spirit. What is power, anyway?
"Ability, whether physical, mental or moral, to act; the faculty of doing or performing something; capacity for action or for performance or receiving external action or force; capability of producing or undergoing an effect, whether physical, mental, moral."
