We hope for emotional amnesia.
Forgiveness is a conscious decision to not allow oneself to be emotionally controlled by the negative actions of someone else.
Unforgiveness is like drinking poison and expecting the other person to die.
Our Father who art in heaven, hallowed be thy name. Thy kingdom come. Thy will be done on earth as it is in heaven. Give us this day our daily bread, and forgive us our trespasses, as we forgive those who trespass against us, and lead us not into temptation but deliver us from evil. For thine is the kingdom, and the power, and the glory, forever. Amen.
Whenever you stand praying, forgive, if you have anything against anyone; so that your Father in heaven may also forgive you in your trespasses.
Mark 11:25
New Revised Standard Version (NRSV)
Do not judge, and you will not be judged; do not condemn, and you will not be condemned. Forgive, and you will be forgiven; give, and it will be given to you. A good measure, pressed down, shaken together, running over, will be put into your lap;
for the measure you give will be the measure you get back.
Luke 6:37-38 (NRSV)
In other words, how can we repent and come to God, when we believe that the sins of others against us are greater than our sins against God? To put it another way, how can we accept forgiveness from God through Jesus Christ, if we are more righteous than our fellow humans who sin against us? The sins that others commit against us can in no way be compared to the sins that we (and they) commit against God. If we fail to see that, then we remain self-righteous before God, because what they did to us is worse than what we have done against God. We cannot receive the righteousness of God through faith if we maintain and hold to our own self-righteousness before the eyes of God.
