Jesus said that he came that we might have life and have it abundantly (John 10:10). I cannot subscribe to the popular prosperity theology that's rampant in our culture which links abundant life to material wealth. Some of the most alive people I've ever met were people who were poor and had short life spans because of where they lived. They invested in relationships not things and conversely, those who spent time heavily invested in things often struggled with relationships.
If we're really honest with ourselves, we'd acknowledge the fact that we are all walking dead. That's right - we all live under a terminal condition ... we all have a death sentence hanging over our heads. We just don't know when, where or how.
So if you began to, as the Tim McGraw song goes, live like you were dying ... what would be different in your life?
