And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. – John 1:14
This is what Christmas is all about to me. Jesus (God) became flesh (human) and came down and dwelt among us. He blessed us, He healed us, He taught us, and then He gave HIS life to pay the penalty for our sins. And then He offered us Eternal Life if we would only believe in Him! He also promised to come back and get us one day.
That is a lot to celebrate!
