So let me tell you a story.
One day a dad took his younger son outside to show him something. He brought a hammer, 50 nails, tongs and some paste. They went to this big wooden fence in the backyard.
-Son, I want you to nail all of these nails in to this fence. I don't care where you nail them just do it as quick as you can.
So he did and within 15 minutes he had nailed them all in to the fence.
-That was quick my son. Now I want you to take this tongs and pull them all out.
He looked at at his dad with a big questionmark in his face but did as his dad had told him to.
After pulling all the nails out of the fence he got his dad to show that he was all done.
-Good job my son. But look at all the holes. Not pretty! Here, take this paste and fill those holes for me.
-What? First you want me to nail 50 nails into the wall. Then you want me to pull them out and now you want me to fill all the holes with this paste?
-Yes, son. Just do it. I will tell you later why I made you do all this. Now carry on.
After several hours all the holes were filled but you could of course see where they used to be.
-Very good!! You did a good job. I'm proud of you. And now I will tell you why I made you do all of this. It's very easy to hurt somebody. Much more easier than nailing those nails into the wooden fence and that was not to much work, was it? And it's harder to say that you are sorry or to be forgiven. Like you discovered pulling the nails out of the fence, right? Finally as you can see it took alot of time to fill all these holes and yet you can see where they used to be. What I mean by this is: Even though you have said that you are sorry and have been forgiven there will always be trails and scars. You can not erase them. They will always be there...
-So think twice my son...It's easy to hurt somebody, harder to say you're sorry, it takes time to be forgiven and the scars are there forever!
