Man…

And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world. — John 8:23 KJV

Quite literally. Some might think humans are from somewhere else, maybe from the stars above, but to the contrary, we are dust indeed.

“And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.” Matthew 10:14 KJV

A simple symbolic act full of significance.

Remember Genesis 2:7 and 3:19?
