One child, one teacher, one book, one pen can change the world. (Malala Yousafzai, Pakistani, youngest-ever Nobel Prize laureate)
When we look at some of the problems in our world, such as illiteracy or poverty, we often hope for some kind of mega-program that will solve those issues: a massive literacy effort, a world-wide attempt at eradicating poverty. These are noble ambitions, of course, but as Yousafazai has suggested, it will more likely happen one rescued person at a time.
The one who sows righteousness reaps a sure reward (Proverbs 11:18).
