A wise sage once said "And forgive us our debts, as we forgive our debtors." It seems forgivness is hinged and known in the measure we are able to forgive others. Why is that? If we harbor unforgivness to others or even ourselves, that which we do not forgive holds us and those who offended, to that offense. It is like a blister that does not heal and just continualy festers.
For the act of forgiving a debt or offense, is much like in modern times a loan we owe on something. If your creditor told you today, "Yes you owe me 5000 dollars to be paid for yet another 24 months in installment payments". You then are still indebted to the creditor for yet 24 months, until you have paid in full all that is owed.
Now if the creditor were to say, "Here is the ledger and the amount still owed but I will now forgive you this debt", it is then you are realeased from the debt now!
This works also in human relationships. If someone has wronged us and we do not forgive them you as the creditor are bound to them as they are to you until such a time as we will clear the ledger to forgive them. It is then the hurt is released first in you, to release that hurt, but also the person whom did the hurting is released. How many people today hold on to the hurts by others to the dividing of families.
An over arching principle of life is every seed bears after its own kind. You sow unforgivness, which fruit becomes bitterness and sorrow, you reap unforgivness bitterness and sorrow.
You sow forgivness with the fruit of release and freedom, you reap the same.
Forgivness is a very powerfull concept that reaches into every avenue life. That which is not forgiven causes bondage until one can forgive.
