I have thought forgiveness was synonymous with excusing an action and so have left a room vacant for unforgiveness in the inn of my heart.
But I have realized that forgiving someone does not excuse the action of the one who wronged me. But it does keep the spectre of bitterness from taking up residence within. The wrong is not allowed to fester and grow into something even worse.
Reconciliation may occur and forgiveness comes with that invitation, but that RSVP may not be answered. I am only one half of the equation.
Forgiveness is primarily for my benefit. That room inside is not empty. Rather it is filled to overflowing with the friends of forgiveness; love, peace, joy, kindness, and healing who infect the entire inn with their festivities.
