Nothing and Yet Everything

My 16 year old step-son was asked "How do we reconcile the ideas from the Bible that we are nothing in this world and yet everything to our Heavenly Father?"  This was his answer:

"In our hearts there is good and bad.  Whether we act on the good or bad intentions is our own decision.  When we act on the good and pure intentions, God sees us as His children and the worldly man sees us as nothing.  When we act on the bad and evil intentions God sees us as nothing because we are moving away from him and closer to Satan.  When we sin the worldly man accepts us and sees us as important."

In the great scheme of things, when we consider the vast universe, we are nothing.  One of my favorite quotes is from the movie Tombstone when Wyatt Earp's brother Morgan says, "Look at all the stars.  You look up and you think, God made all this and He remembered to make a little speck like me."  But to Heavenly Father each one of us is important.  He knows us 'from our Mother's womb' and has counted the hairs on our head.  We are each a part of His intricate plan.

We are nothing...
Genesis 3:19 In the sweat of thy face shalt thou eat bread, tiill thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

And yet Everything to Him.
Matthew 10:29-31  Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father.  But the very hairs of your head are all numbered.  Fear ye not therefore, ye are of more value than many sparrows.
