'Power of God' in the Bible

For we are not as many are, which chop and change with the word of God: but even out of pureness, and by the power of God and in the sight of God, so speak we in Christ.

in the words of truth, in the power of God, by the armour of righteousness of the right hand and on the left hand,

And verily, though it came of weakness that he was crucified, yet liveth he through the power of God: and we no doubt are weak in him; but we shall live with him, by the might of God among you.
