'Power' in the Bible

But when the Pharisees heard this they said, "He does not cast out demons except by the power of Beelzebul, the ruler of demons!"

Jesus answered them, "You are deceived, because you don't know the scriptures or the power of God.

Then the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man arriving on the clouds of heaven with power and great glory.

Jesus said to him, "You have said it yourself. But I tell you, from now on you will see the Son of Man sitting at the right hand of the Power and coming on the clouds of heaven."
