Why Do We Find It So Hard to Forgive?
One reason we resist forgiving is that we don't really understand what forgiveness is or how it works. We think we do, but we don't.
The first step to understanding forgiveness is learning what it is and isn't. The next step is giving yourself permission to forgive and forget, letting go of the bitterness while remembering very clearly your rights to healthy boundaries.
• Forgiveness is returning to God the right to take care of justice. By refusing to transfer the right to exact punishment or revenge, we are telling God we don't trust him to take care of matters.
• Forgiveness is not letting the offense recur again and again. We don't have to tolerate, nor should we keep ourselves open to, lack of respect or any form of abuse.
• Forgiveness does not mean we have to revert to being the victim. Forgiving is not saying, "What you did was okay, so go ahead and walk all over me." Nor is it playing the martyr, enjoying the performance of forgiving people because it perpetuates our victim role.
• Forgiveness is the act of pardoning an offender. In the Bible, the Greek word translated “forgiveness” literally means “to let go,” as when a person does not demand payment for a debt. Jesus used this comparison when he taught his followers to pray: “Forgive us our sins, for we ourselves also forgive everyone who is in debt to us.” (Luke 11:4)
 Likewise, in his parable of the unmerciful slave, Jesus equated forgiveness with canceling a debt.—Matthew 18:23-35.
• We forgive others when we let go of resentment and give up any claim to be compensated for the hurt or loss we have suffered. The Bible teaches that unselfish love is the basis for true forgiveness, since love “does not keep account of the injury.”
1 Corinthians 13:4, 5.
