To cast the burden means really to insist upon harmony and peace of mind, and to cease from worry and anxiety there and then. This leaves you free to go about your business in a serene frame of mind, following upon which, in due course, you find your problem solved. ~ Fox, Emmet. Find and Use Your Inner Power (p. 58). New Albany. Kindle Edition.

Cast. Throw, fling, pitch, hurl, lob. chunk.
Cast your cares, your anxiety, your cares,
your troubles, your millstone, your load,
your onus, your responsibility, your load.
Cast your burden on the Lord.
God, I offer myself to Thee to build with me
and to do with me as Thou wilt.
Relieve me of the bondage of self,
that I may better do Thy will.
Take away my difficulties,
that victory over them may bear witness
to those I would help
of Thy Power, Thy Love, and Thy Way of life.
May I do Thy will always!
Cast your burden on the Lord,
And He shall sustain you;
He shall never permit the righteous to be moved.
(Psalm 55:22-23 New King James Version)
My difficulties, my burden are Yours.
Your will, not mine be done…THANK GOD!
