"Unforgiveness has rightly been called the cancer of the soul,
and it is perhaps the greatest block
to emotional and spiritual healing.
It gives room to bitterness, anger, hurt, rage
and other tangled emotions
that block our emotional and spiritual growth.
Unforgiveness creates an inner prison,
and the only key to open the prison door is forgiveness.
Our prayer should always be that God would overcome our pride,
stubbornness and desire for revenge,
and bring us quickly to forgive
so that we may receive his abundant mercy and forgiveness ourselves"
Mike Flynn and Douglas Gregg, Inner Healing, pg 93
