We thank God always for all of you as we mention you constantly in our prayers, because we recall in the presence of our God and Father your work of faith and labor of love and endurance of hope in our Lord Jesus Christ.   1 Thessalonians 1:2-3 NET

So in addition to being the moment the Savior came into the world, Christmas marked the beginning of the legacy of eternity's greatest King.

Jesus Christ will continue to reign long after the kings and kingdoms of this world pass away, and we will get to live under the covering of His perfect love forever if we seek Him, accept His outstretched hand, and declare Jesus as our risen Saviour.
