'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.

So get rid of all uncleanness and all that remains of wickedness, and with a humble spirit receive the word [of God] which is implanted [actually rooted in your heart], which is able to save your souls.

So too, faith, if it does not have works [to back it up], is by itself dead [inoperative and ineffective].

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.

But He gives us more and more grace [through the power of the Holy Spirit to defy sin and live an obedient life that reflects both our faith and our gratitude for our salvation]. Therefore, it says, “God is opposed to the proud and haughty, but [continually] gives [the gift of] grace to the humble [who turn away from self-righteousness].”

There is only one Lawgiver and Judge, the One who is able to save and to destroy [the one God who has the absolute power of life and death]; but who are you to [hypocritically or self-righteously] pass judgment on your neighbor?

Confess therefore your offences to one another, and pray for one another, that ye may be healed. The fervent supplication of the righteous man has much power.
