Developing in the Dark

Everything in life goes through a process. A baby grows in their mother's womb, a seed is planted in the soil, and diamonds are made from the pressure found deep within the Earth's core. What is common in these three examples? They are all very dark and isolated places. I have come to learn that God develops our character and purpose in that very same manner--within the darkroom.
But remember...what's developed in the dark will shine in the light.
