Even in life, changes can be mild going from season to season. Having kids, hair changes to gray, kids grow up and get married, the normal progression of life. It’s expected but it can leave us feeling bare just like a tree that just lost its leaves.
This picture is mild next to what some people experience after a big storm. Still, sometimes a continual persistent wind that rips the branches off one by one and causes the needles to fall continuously on a person can be just as damaging.
The story about Naaman and Elisha can be found in the Old Testament, 2 Kings, Chapter 5.
