From today's devotional
The word of God spread like ripples on a pond where, from a single center, each wave touches the next, spreading wider and farther. The gospel still spreads this way today.
You don't have to change the world single-handedly-it is enough just to be part of the wave, touching those around you, who in turn will touch others until all have felt the movement. Don't ever feel that your part is insignificant or unimportant.
