Recently I saw something on CNN website which made me cry, 8 years old boy and his 5 years old brother working in a market and earning few cents a day.
This man had no idea when he befriended that boy that that act would spark a major ministry work, but God knew. Each act of kindness has a ripple effect and we have no idea how far the ripples will spread. As the song title says, "Little is much when God is in it".
