I would say that I'm definitely someone who doesn't live in the past. You can do me wrong, and the next day I'm ready to be friends again. But, every so often I've found myself saying I can or can't do something because of what has happened in my life. If we're not careful we can live defined by our past. Maybe who God has designed me to be hasn't always lined up with my character, but there's hope in realizing that no matter what that doesn't disqualify me.
I like what it says in Isaiah 43:18-19
