'Power' in the Bible

Immediately Jesus, perceiving in himself that the power had gone out from him, turned around in the crowd, and asked, "Who touched my clothes?"

He said to them, "Most certainly I tell you, there are some standing here who will in no way taste death until they see the Kingdom of God come with power."

Jesus answered them, "Isn't this because you are mistaken, not knowing the Scriptures, nor the power of God?

Then they will see the Son of Man coming in clouds with great power and glory.

Jesus said, "I am. You will see the Son of Man sitting at the right hand of Power, and coming with the clouds of the sky."
