'Powers' in the Bible

And, without growing weak in faith, he could contemplate his own vital powers which had now decayed--for he was nearly 100 years old--and Sarah's barrenness.

When we were living in the flesh [trapped by sin], the sinful passions, which were awakened by [that which] the Law [identifies as sin], were at work in our body to bear fruit for death [since the willingness to sin led to death and separation from God].

For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,

Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
