Chiaroscuro

“…if our days were routinely sun-filled, peaceful, tranquil, predictable, without conflict, their very serenity would soon seem flat, humdrum, and stale. God allows his brilliance to be highlighted by shadow and his summer warmth to be contrasted with winter chill so that we will know the difference and appreciate the light and warmth. There is purpose in the divine chiaroscuro.” ~ Luci Shaw
