'Power' in the Bible

But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:

No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.

As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.

Then saith Pilate unto him, Speakest thou not unto me? knowest thou not that I have power to crucify thee, and have power to release thee?

Jesus answered, Thou couldest have no power at all against me, except it were given thee from above: therefore he that delivered me unto thee hath the greater sin.
