forgiveness

In the story below, Jesus is trying to teach Peter (and the others) about the importance of forgiveness (ruler forgives a large debt to a man who refuses to forgive a small debt). Last night I was trying to teach this parable to my two sons (10 and 5 yrs old) and I found myself using "forgiveness" as a type of currency. I said that:

1. I had a right to collect 100 pennies from my ten year old who had a right to collect 1 penny from my five year old.
2. i forgive his debt of 100 pennies which is the same as giving him his pennies back even though I had a right to keep them. (and that if I could give my older son 100 pennies for free, then surely it would not be too much to ask of him to give one of those pennies to my younger son to share in the "bounty"
3. I told them that forgiveness is like those pennies (when you forgive someone , you are giving back to them something you had a right to keep.)
4. If I give my older son 100 "forgiveness's", then surely he can give one "forgiveness" to my younger son.
5. God gives us an infinite number of "forgiveness" coins and surely we can give a few to those around us.

they both got it !! (and I later looked up with pleasure to find that the word forgive comes from an 11th century word meaning "to give"(Middle English, from Old English forgifan, from for- + gifan to give) according to Webster's Dictionary

How well do we share God's currency ?

Matt: 23 “For this reason the kingdom of heaven may be compared to a certain king who wished to settle accounts with his slaves. 24 “And when he had begun to settle them, there was brought to him one who owed him ten thousand talents. 25 “But since he did not have the means to repay, his lord commanded him to be sold, along with his wife and children and all that he had, and repayment to be made. 26 “The slave therefore falling down, prostrated himself before him, saying, ‘Have patience with me, and I will repay you everything.’ 27 “And the lord of that slave felt compassion and released him and forgave him the debt. 28 “But that slave went out and found one of his fellow slaves who owed him a hundred denarii; and he seized him and began to choke him, saying, ‘Pay back what you owe.’ 29 “So his fellow slave fell down and began to entreat him, saying, ‘Have patience with me and I will repay you.’ 30 “He was unwilling however, but went and threw him in prison until he should pay back what was owed. 31 “So when his fellow slaves saw what had happened, they were deeply grieved and came and reported to their lord all that had happened. 32 “Then summoning him, his lord said to him, ‘You wicked slave, I forgave you all that debt because you entreated me. 33 ‘Should you not also have had mercy on your fellow slave, even as I had mercy on you?’ 34 “And his lord, moved with anger, handed him over to the torturers until he should repay all that was owed him. 35 “So shall My heavenly Father also do to you, if each of you does not forgive his brother from your heart.” from the NASB.
