I Cor. 13:5 - "Love thinks no evil" KJV
The word is "logizomai" = an accounting term
It would be used in the keeping of a perfect record for financial purposes (very necessary for us in terms of the IRS, but very damaging for a walk with God).
Let's be honest, it hurts when someone hurts us. And we don't want to get hurt again because after all, it hurts!
But what happens when we keep lists? Those lists minister tremendous emotional power to our lives and they are not healthy emotional powers! Hurt! Anger! Fear! Which in turn lead to anxiety and bitterness.
These "emotions" trigger us to build walls around ourselves in order to protect us from others. We say things like, "I will never let anyone get close to me again. I will never give my heart away again!"
Case in point:
"It is easier to win a fortified city than it is to win a wounded brother."
Put simply, the walls we build work. They keep people out!
Let's put this verse into history. Alexander the Great decided to conquer a greatly walled city named Tyre and it took 10 years to build it. And what did the Proverb say? It is easier to win the city of Tyre, than it is to win a wounded brother.
THE WALLS WE BUILD TO PROTECT OURSELVES WORK! They keep people out.
The verse has a final phrase though:
"and his contentions are like bars"
Did you see it?
When we build our walls to protect ourselves, our walls, our fortresses that we build to keep people out, morphs into a prison. This prison locks us in, and this beautiful creation that God made, CANNOT GET OUT OF THIS PRISON OF HIS OWN MAKING! Why would we want to do that to ourselves? Why would we want to put ourselves in prison?
Love keeps no lists.
If we keep a list and refuse to forgive, not only are we most likely going to fail in loving the one who hurt us, but we will also fail to be loving ourselves.
