all about perspective

i came across these words today by the great Puritan preacher, Jonathan Edwards:

It becomes us to spend this life only as a journey toward heaven...to which we should subordinate all other concerns of life. Why should we labor for or set our hearts on anything else, but that which is our proper end and true happiness?

i couldn't help but wonder how different our world might be--how we'd live and spend our days, the love we'd share, the joy and peace we'd experience--if more of us lived out these words??
