'Power' in the Bible

Jesus answered them, "You are mistaken because you don't know the Scriptures or God's power,

Then the sign of the Son of Man will appear in the sky, and all "the tribes of the land will mourn' when they see "the Son of Man coming on the clouds of heaven' with power and great glory.

Jesus told him, "You have said so. Nevertheless I tell you, from now on you will see "the Son of Man seated at the right hand of Power' and "coming on the clouds of heaven.'"
