The title sums it all up! I happened to be in the right place at the right time. The photograph speaks on many levels, and words seem to be unecessary. There is light and there is shade; a reflection of our own lives, whatever might be happening as we read these words.
Take a moment just to observe the photograph and perhaps write down thoughts and impressions that may pop into your mind. Perhaps look at it later in the day, see if there have been any changes in how you respond.
Let the Spirit of life and truth speak into your moments.
