We have all had people take advantage of us, stab us in the back, mentally or physically abuse us, and any other number of things.  The hardest part is forgiving those people and moving on with our lives.  There are many times we will just hang on to those injustices as if we are letting those people off the hook if we forgive them.  There are many reasons to release those events, the biggest reason is so that we can move forward with our own life and reap the blessings from God.
