Genesis tells us that God created man out of the dust and breathed life.  Throughout Scripture we are also told that it is to dust that we return when we die.  In the grand scheme of eternity we are here on earth for only a brief time, just as a vapor appears and disappears so quickly.  Rather than wasting that precious time by following the ways of the world, we need to follow God’s call on our lives to honor Him in all that we do, remembering that not only do we represent Him to the world but we also carry Him around in us by His Spirit.  God has given us a reason to be alive, to serve Him in everything, and at no point in our life should we ever take a break from fulfilling that purpose.
