But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. (Gal 4:4-5)
The Incarnate Son of God, who became flesh and dwelt among us, came at the appointed time to fulfill the Law and the prophets, to not just be a babe in a manger but to be a sacrifice for sins. He came not to live but to die, to satisfy the justice of God demanded by the Law and making propitiation for the sins of His elect sheep. The image of Christmas is not merely of a manger or figures in a creche but rather of a lonely cross where He would suffer and die. Without the cross, there is no Christmas. Praise God for His Son who left behind a perfect and glorious fellowship with the Father to live a life of poverty so that we may someday enjoy that same fellowship! Thank God for the redeeming sacrifice and the undeserved adoption that we who know Him and are known by Him enjoy.
