Walking down the sidewalk one day, I saw something interesting: a tree was growing out of a small crack, and it was breaking the concrete itself. In what would seem to be the worst place ever, life was growing, and overcoming the massive odds against it.
In the parable of the sower, the man throwing seeds threw them on all the types of ground. (Luke 8) We should do the same spiritually, because no matter how unlikely the place looks, even if it's paved over with concrete, you never know when that one tiny crack will allow a seed to sprout up with explosive, abundant, powerful growth. Those with the most stacked against them can be the strongest examples. Give them a shot.
