The words of Thomas Jefferson defined our nation; the words of Abraham Lincoln strengthened its resolve at a time of unprecedented crisis; the words of Martin Luther King effected a moral revolution; the words of Winston Churchill turned back an evil empire. Words--even puny human words--pack enormous power. Imagine the power of God's Word, made flesh in Jesus Christ. It unleashed a force that, 2000 years later, continues to change the world. Christmas is the day when we celebrate that power.
