I feel the scar and the people around me see it. It is a constant reminder of these complicated memories. Yet as the physical wound heals, fewer people now say, "oh my, what happened," or, "how did u get that scar?". The physical scar is less noticeable and far less commented on, yet my wife and I (& other family members) will always carry the emotional scars. My wife will always see the scar, whether actually visible or not, when she sees the back of my head. For my part, I will always feel the scar. Fortunately, we have a God who understands the memory that lives in scars.
We talk about Christ being on the cross, but that experience came with significant scars. Hanging on the cross, from the outside, seems like a wholly terrible experience, but that terrible moment was proceeded by a life that brought many blessings. The scars of Christ were not just a negative memory, but a reminder of the loving acts committed by Christ, as well. The scars of Christ are reminders of the good that came out of a bad situation.
I think that all of us are confronted by scars sometimes. We all find troubles that leave marks on us whether physical marks or emotional. It is up to us whether we will dwell on the passing negative experience or whether we will find good in the midst of angst and trouble. Christ endured the bad that we would all know the good (His Love). When we experience trouble we must look to Christ, so that through Christ's wounds, we can experience joy even in the midst of our own pain, our own wounds, our own scars.
