"There is a class of men and women in all Protestant communities who think it is a very neat thing to do good randomly. They sow broadcasting cheap seed, content to reap nothing at all, and pleasantly disappointed if they find here and there a stalk of corn to reward their sowing. They do not prepare their ground, they do not cultivate it at all, but they sow hoping that in some open place a seed may fall and germinate." Timothy Titcomb. 

  I like this quote because I think it is so common with many evangelicals that don't want to get their hands dirty but think they have done their Christian duty if they bring up Christ in a conversation not considering the circumstances, or they hurl a gospel tract or a verse at unwitting strangers. Gospel work is the work of the heart, there are no shortcuts.
