Here's a quote to pierce your heart by the President of World Vision, Richard Sterns:
"I believe that this could very well be looked back on as the sin of our generation. I look at my parents and ask, where were they during the civil rights movement? I look at my grandparents and ask, what were they doing when the holocaust in Europe was occuring with regard to the Jews, and why didn't they speak up? And when we think of our great, great, great-grandparents, we think how could they have sat by and allowed slavery to exist? And I believe that our children and their children, 40 or 50 years from now, are going to ask me, what did you do while 40 million children became orphans in Africa?"
It can be overwhelming to consider what messy, imperfect people like ourselves can do about a problem as big as 147 million orphans in the world. However, one life can make a significant impact with a willing heart, and a simple prayer like this, "Lord, I am willing to fight for what is yours, burden me."
