Nona Freeman, the great missionary, once related this story about something that happened in Ghana:
A student from a college in Carbondale, Illinois gave another student from Ghana a tract. In Ghana when a student goes away to college everyone in their tribe contributes something but when they come home they all expect something in return. The student handed the tract he received to someone as a gift. As a result of that anonymous person who passed out a tract. The man who received the tract found God and his family also. Missionaries were sent when the family wrote requesting them and over 600 people were baptized in Ghana. You don’t see immediate results from your labor many times but you will be rewarded.
