Power tends to dissipate.  It must be renewed.  A branch must have the vine.  An appliance needs to be plugged into an electrical source.  Batteries have to be recharged.  Energy must be renewed.  We are not self-sufficient.  We are not the source of power.  We are channels through which it flows.  If we seek to own power, we become manipulators.  If we focus on it, we become idolatrous.  If we take credit for it, we become corrupted.  The Father is looking for humble vessels through whom He can bless the world.

“I pray that, according to the riches of his glory, he may grant that you may be strengthened in your inner being with power through his Spirit.” Eph 3:16 (NRSV)
