'Power' in the Bible

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].

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?

Therefore, confess your sins to one another [your false steps, your offenses], and pray for one another, that you may be healed and restored. The heartfelt and persistent prayer of a righteous man (believer) can accomplish much [when put into action and made effective by God—it is dynamic and can have tremendous power].
