'Power' in the Bible

Because you have the knowledge that the testing of your faith gives you the power of going on in hope;

But let this power have its full effect, so that you may be made complete, needing nothing.

And the tongue is a fire; it is the power of evil placed in our bodies, making all the body unclean, putting the wheel of life on fire, and getting its fire from hell.

There is only one judge and law-giver, even he who has the power of salvation and of destruction; but who are you to be your neighbour's judge?

So then, make a statement of your sins to one another, and say prayers for one another so that you may be made well. The prayer of a good man is full of power in its working.
