scar tissue

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.
All praise to the God and Father of our Master, Jesus the Messiah! Father of all mercy! God of all healing counsel! He comes alongside us when we go through hard times, and before you know it, he brings us alongside someone else who is going through hard times so that we can be there for that person just as God was there for us. (2 Corinthians 1:3-4 MSG)
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.
