A child is born who can stop the hand of God, who can overthrow the power of the maker of this world and free the slaves of sin. No mere child could be so powerful unless that child was also God. And how has He stopped the hand of wrath, overturned the death sentence of the whole human race and empowered man to resist the might of the devil and his cohorts? By becoming weak, by taking on our nature. He empowered our nature by subjecting Himself to our sentence, not just of death but of misery as a frail mortal. He knows what it is to be one of us. The Eternal Word, being strong, became weak.
