Jesus said, “Father, forgive them, for they do not know what they are doing.”
Jesus taught a lot about forgiveness. He said that we are not to forgive seven times but 77 times or seventy times seven. Jesus told us not to retaliate when someone strikes us but to turn the other cheek.
Of course Jesus set the example for forgiveness when dying on the cross. He asked for forgiveness for those who had persecuted Him and crucified Him.
In the Lord’s Prayer Jesus teaches us how to pray. We are told to pray, “Forgive us our debts as we also have forgiven our debtors.” To pray this prayer means to be forgiven in the way that we forgive others.
If we are unwilling to forgive others, we have no right to ask God to forgive us. God has forgiven us of all of our sins. We have no right to hold something over someone who has done us wrong.
Of course not only did Jesus set the example of forgiveness, He made forgiveness possible in the first place. Without Jesus’ death and resurrection we have no right to ask for forgiveness. But because of it we need to follow Jesus’ example and forgive others even when it is hard to do so.
