'Power' in the Bible

But we have this treasure in clay jars, so that the extraordinary power belongs to God and does not come from us.

by truthful teaching, by the power of God, with weapons of righteousness both for the right hand and for the left,

But he said to me, "My grace is enough for you, for my power is made perfect in weakness." So then, I will boast most gladly about my weaknesses, so that the power of Christ may reside in me.

For indeed he was crucified by reason of weakness, but he lives because of God's power. For we also are weak in him, but we will live together with him, because of God's power toward you.
