Genesis 3:19 “In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou [art], and unto dust shalt thou return.
Job 42:6 “Wherefore I abhor [myself], and repent in dust and ashes.”
Luke 8:15 “But that on the good ground are they, which in an honest and good heart, having heard the word, keep [it], and bring forth fruit with patience…”
Man is dust; powerful dust that can create if it is part of something greater, rather than just being dust in the wind. When man lowers himself [in humility] and returns to the ground (fruitful soil) and becomes part of the “ground” he is made from, then he can produce some good “fruit”. Be one with the ground that creates good fruit.
