Cut the umbilical cord to yesterday. Although we can't change history, we change the effect the past has on the future.
When you don't forgive you permit your enemies to live rent free in your head -evict them today.
I like to remind myself, as a parent, that God holds me responsible to, not for, my children!
Don't drag anchors of unforgiveness into your relationships. Forgive who you need to forgive. Reach out to someone who may be able to help you work this through. Don't drag around those things that "encumber" you.
Pray to God, but row towards shore.
