Forgiveness

70 x 7 that is what Jesus tells us to forgive.
What is forgiveness? To me it is the act of letting go of wrongs committed against you by someone else. When someone wrongs you we are instructed to forgive those who have wronged us. In the Lords Prayer there is the line "Forgive us our sins,as we forgive those who sin against us.". When we ask God to forgive us of the wrongs we have committed against Him and His teachings, He in return asks us to forgive those who have wronged or sinned against us. I think that if we have unforgiving hearts it can lead to a life of unrest, anger and sickness. Our hearts are poisoned by the unforgiveness and I do believe that can affect our health.
Even the Mayo clinic acknowledges forgiveness as a healer (see story ttp://www.mayoclinic.com/health/forgiveness/MH00131 )

Unforgiveness can keep us from blessings that God may have for us, because our hearts and minds are so tied up with the wrongs we feel are committed against us that most often we do not see what God is trying to do in our lives. Forgiving some one who has hurt us can be extremely difficult (read Corrie Ten Booms story here http://www.crossway.org/product/663575723080 )
Corrie Ten Boom had to forgive her oppressors `When you and I are willing to see our need for God's forgiveness, He is willing and able to forgive our sins. The Bible says that "all have sinned and fall short of the glory of God" and that "the wages of sin is death" (Romans 3:23; 6:23). But it goes on to explain that "God demonstrates His own love for us in this: While we were still sinners, Christ died for us" (Romans 5:8).`` Corrie Ten Boom.

Please work to forgive those that have wronged you. It may be difficult, but with Gods help you can do it.
