>Put no trust in oppression; in robbery take no empty pride;
Though wealth increase, set not your heart upon it.
God spoke once, and twice have I heard the same,
That power belongs to God.
Psalm 62:10f

So, don’t even try to be powerful – just be yourself.
That is power enough – for each day to turn on the light.

The prayer that concludes today’s psalm (according to the Daily Office):

O God, teach us to seek security,
not in money or theft,
not in human ambition or malice,
not in our own ability or power,
but in you, the only God,
our rock and our salvation.
