Am I just 'passing through'?

There's a line of thought among Christians that we are just 'passing through' this world and that our real home is Heaven...I used to believe this, too, although deep down I knew I loved this life and loved earth (in spite of the troubles that happen in this life). I no longer live this way or believe this way. In response to a blog post I read recently I was able to articulate my beliefs on this...

I believe that Earth is my home, and that God created me to live here in relationship with Him and in community with others, honoring them and creation. I believe that Jesus' work on the cross freed me from (among other things) religious strictures that placed man's ideas of how to be close to God with a recalibration of God's original intention (direct relationship with Him)...I don't believe that my focus should be on what happens after I 'pass through' this life (and yes, I do also believe that people go to heaven when they die). I believe that I have been given the Earth as a gift and that as a child of the Creator I bear responsibility in making this world a place that reflects the 'Kingdom' from which it was made. When I place Papa at the center of my being I will live as Papa intended and help to make this world a better place. I believe that there will be a new heaven and new earth at some point and that I will be a resident of the new earth that operates within an 'open heaven' that gives it it's life.
