The key to forgiveness is giving up the grudge. The primary reason to give up the grudge is not because we are all sinners and only God can judge us but rather because of the tremendous harm it does us to hold the grudge.
A rattlesnake, if cornered, will become so angry it will bite itself. That is exactly what harboring hate and resentment against others isa biting of oneself. We think that we are harming others in holding these spites and hates, but the deeper harm is to ourselves. Forgiveness is for the victim's physical and mental health, NOT the perpetrator's.
Forgiveness, in fact, is the key to freedom. By reaching past our hatred to seeing the other's humanity and releasing them from any hurts done to us, our feelings can begin to change. We are responsible for our own behavior. We are not responsible for other peoples behaviors and actions; nor are they responsible for ours.
Put your trust in Gods power. Ask God for healing. In the midst of wrong, love can be recovered whether or not justice is served. Forgiveness returns us to tranquility, wholeness and the ability to love fully. If you remain in your anger, your arrogance, your pride, or your pain, you are like the oak, which ultimately will be felled by the numerous ax blows at your soul.
Your most important freedom is your attitude, your reaction to circumstances. Choose your own way. Dont let circumstances dictate the way. Move on. Dump the baggage. Let go..."Forgive"...Heal your soul and mind...
