I have heard these words twice over the past week, so thought you may find them helpful - "Flowers soak up the sun and rain in the day time, but they do their growing in the dark." To put it in a different way - we don't grow through the good times, but rather through the difficult times.
"If the thunder is not loud, the peasant forgets to cross himself." - Russian proverb "A smooth sea never made a skillful mariner." - English Proverb
May we be deeply conscious of God's spirit with us in the dark times. The growth will follow.
