Wounds can heal with time, but healed wounds always leave scars, reminding the person of the wound. Deep, extensive, or infected wounds may not heal on their own and require surgical removal of damaged skin and tissue. Reconstructive surgery can be done, bringing in new tissue or skin, resulting in a modified or renewed appearance. Yet, even with the best surgery, a faint scar will be detectable. Scientific research has yet to find a way of complete wound healing or tissue regeneration without leaving a scar. God in His infinite wisdom designed the human body in this way for a reason. Similarly, healed emotional wounds also leave scars, as shown in this book. Often in this life, the past gets in the way of the future. Deep emotional scars can be difficult to deal with. However, unless the root cause is dealt with or removed, true progress cannot be made.
