For love of His rebellious children and for His own glory, the Father sent His son to a rebellious world. The Son obediently humbled Himself, and the omnipotent Word of God entered His own creation as a weak, wordless, squalling baby boy. He died in our place, he rose in total victory, and the Spirit moved in the hearts of those He had chosen to receive Him . . .
