The eternal now

Have you ever considered the possibility that we are living in eternity?  I don't mean that we will live forever on Earth, no matter how good medical advancements are.  One time, in bible study, we talked about living our eternity NOW.  That is, if we desire Heaven, we should/would/could live as though we are in Heaven.  Not the "I-can-abdicate-all-my-responsibilities" lifestyle, but the choice to live as a conscious Catholic Christian, treating others with love and mercy.
