'Power' in the Bible

I remember your sincere and unqualified faith [the surrendering of your entire self to God in Christ with confident trust in His power, wisdom and goodness, a faith] which first lived in [the heart of] your grandmother Lois and your mother Eunice, and I am confident that it is in you as well.

For God did not give us a spirit of timidity or cowardice or fear, but [He has given us a spirit] of power and of love and of sound judgment and personal discipline [abilities that result in a calm, well-balanced mind and self-control].

So do not be ashamed to testify about our Lord or about me His prisoner, but with me take your share of suffering for the gospel [continue to preach regardless of the circumstances], in accordance with the power of God [for His power is invincible],

holding to a form of [outward] godliness (religion), although they have denied its power [for their conduct nullifies their claim of faith]. Avoid such people and keep far away from them.

and how from childhood you have known the sacred writings (Hebrew Scriptures) which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus [surrendering your entire self to Him and having absolute confidence in His wisdom, power and goodness].
