Philippians 4:13-14

Brothers, I do not count myself to have attained, but this one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal to the prize of the high calling of God in Christ Jesus.  

Our pasts are not a weight that we should keep carrying on our backs.  God has forgiven us, and we need to forgive ourselves so we can move forward.  We look at our current lives with every experience we have had.  When we let the negative experiences go and let God heal, we can now look at our lives with the eyes of Christ.
