I am working on a sermon on finishing well. I have been wondering why some Christians are able to withstand all kinds of adversities and finish their lives faithfully and others either never get in the race, lose their enthusiasm or drop out of the race completely. I have been studying the Parable of the Sower and some other parables that Jesus taught. Can anyone suggest resources where I can find this kind of information? What are the characteristics of those who finish well? What do they do? What do they refrain from doing? What makes the winners different from the others?
