A Quote by Martin Luther on anxiety, belief, commitment, god, heart, labor, quiet, serenity, sleep, tranquility, and work

He who believes in God is not careful for the morrow, but labors joyfully and with a great heart. "For He giveth His beloved, as in sleep." They must work and watch, yet never be careful or anxious, but commit all to Him, and live in serene tranquility; with a quiet heart, as one who sleeps safely and quietly.
