This optimist occupies a human body that just three years ago felt like 25, which has since then taken a…(ahem) "buffeting" [trying not to roll my eyes here]. The optimist makes jokes and laughs about the warranty running out when you turn 50. Then I stop laughing and look for something deeper. I look for the strength found not in a 25-year old body, nor in a body that feels like 25—strength found only in weakness.
When we become Christians, we don't merely choose an eternity in heaven over hell. Rather, we are "born again"; like a newborn child, each of us enters into a new life that we fully inhabit, day-in and day-out. God desires that we pursue a relationship with him every day, in all aspects of life. When we try to live daily life for the sake of his glory, he deems it sacred.
