There is nothing anyone can do to me, no mis-deed, no trespass, no evil done now or in the future that hasn't already been paid for by the blood of Christ. So how can I hold on to anger and bitterness? These are the results of an unforgiving heart. Was Christ's death not enough!? The debt was paid. What a fool I am to think that I should demand more from someone who offends me by seeking my own payment in anger, bitterness, and revenge. Christ blood was more and more and more than enough!
John MacArthur, in his Oct 11 radio broadcast entitled, "The portrait of a new life", says that the way we forgive is the measure of the depth of appreciation that we have for Christ's death for our sins. John goes on to say that it is also a measure of whether we have love in our hearts. Christ's forgiveness of our sins is the ultimate act of love and Eph 4:32 says we should forgive like Christ forgave. So by holding on to anger and bitterness we demonstrate that we don't love. 1 John 4:7 says that those who love know God. By not forgiving we show that we don't love and by not loving we show that we don't know God.
Use forgiveness to gauge the love you show and remember that the offenses against you have been paid for ALREADY. Don't demand more by giving in to your anger! You don't have that right! Was Christ's torture, his beatings, whippings, humiliation, the nails through his feet and hands not enough for you!?
