Living a life of unforgiveness is like leaving the parking break on when you drive your car. Its a drag! It causes you to slow down and lose your momentum. One of the most expensive luxuries that you can possess is unforgiveness toward someone. A deep-seated grudge in your life eats away at your peace of mind like a deadly cancer, destroying a vital organ of life. In fact, there are few things as pathetic to behold as the person who has harbored a grudge and hatred for many years.
