E. T. Sullivan

When God wants a great work done in the world or a great wrong righted, he goes about it in a very unusual way.  He doesn't stir up his earthquakes or send forth his thunderbolts.  Instead, he has a helpless baby born, perhaps in a simple home of some obscure mother.  And then God puts the idea into the mother's heart, and she puts it in the baby's mind. And then God waits.  The greatest forces in the world are not the earthquakes and the thunderbolts.  The greatest forces in the world are babies.
