The Wolf's Law
When bones have small fractures it builds a harder layer of bone, it becomes stronger so the pain becomes more tolerable. its called the wolfs law. when the bones are consistently broken down or constantly loaded with pressure it becomes strong, so strong that it can break through bricks. The heart can work in a similar way it becomes tough enough to conquer. We heal up from hurt, cuts, and bruises so we can overcome it. The heart pumps blood through our veins our pulse elevates so we can put up with pain. Love makes us become brave God designed us in this way so that we would fight and carry on.
