Matthew 18:21-35
21 Then Peter came to Him and said, “Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?”
22 Jesus said to him, “I do not say to you, up to seven times, but up to seventy times seven. 23 Therefore the kingdom of heaven is like a certain king who wanted to settle accounts with his servants. 24 And when he had begun to settle accounts, one was brought to him who owed him ten thousand talents. 25 But as he was not able to pay, his master commanded that he be sold, with his wife and children and all that he had, and that payment be made. 26 The servant therefore fell down before him, saying, ‘Master, have patience with me, and I will pay you all.’ 27 Then the master of that servant was moved with compassion, released him, and forgave him the debt.
28 “But that servant went out and found one of his fellow servants who owed him a hundred denarii; and he laid hands on him and took him by the throat, saying, ‘Pay me what you owe!’ 29 So his fellow servant fell down at his feet and begged him, saying, ‘Have patience with me, and I will pay you all.’ 30 And he would not, but went and threw him into prison till he should pay the debt. 31 So when his fellow servants saw what had been done, they were very grieved, and came and told their master all that had been done. 32 Then his master, after he had called him, said to him, ‘You wicked servant! I forgave you all that debt because you begged me. 33 Should you not also have had compassion on your fellow servant, just as I had pity on you?’ 34 And his master was angry, and delivered him to the torturers until he should pay all that was due to him.
35 “So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses.”

Some people ask me how I can possibly forgive what this person or that person did to me?  As a Christian, my response is...  "In light of what God has forgiven Samson (thousands of sins by internal and external) how can I not forgive another person.  When we truly understand what God has done for us, it changes everything.  I am like the servant who owed 10,000 talents and was forgiven.  So, how can I not forgive others."
