I loved this interesting poem found in Madeleine L'Engle's third book in the 'Wrinkle in Time' series, 'A Swiftly Tilting Planet'. It's beautiful!
In this fateful hour,
I call on heaven with all its power,
and the sun with its brightness,
and the snow with its whiteness,
and fire with all the strength it hath,
and lightning with its rapid wrath,
and the winds with their swiftness along their path,
and the sea with its deepness,
and the rocks with their steepness,
and the earth with its starkness;
All these I place
by God's almighty help and grace,
Between myself and the powers of darkness.
