I wonder if there is an actual medical "purpose" for scar tissue? I may have to ask my cousin's (doctor) husband that some time. The Bible tells us that there is a purpose for the (emotional/spiritual) scar tissue of life's wounds, so I suspect there is in physical scar tissue, as well.
I found this passage back in 2005 when I was grieving the loss of my wife and trying to make some sense of it all. There was a blessed young man who had lost his wife a few years prior who came alongside me during that time that helped me keep my head above water. I can't imagine what I would have done without his shoulder to lean on. This week the passage came to mind again as I spoke to him again for the first time in a while and we both began to lend comfort to another young man who has found himself walking this dark road. It isn't a short road. The wounds still hurt four years later, even after re-marrying. But the "Father of all mercy", the "God of all healing counsel" has been faithful these four years. I pray that somehow He can use these scars for His glory.
