We celebrate the miracle of Jesus' conception to a virgin this time of year and we should. However, I think there's another miracle we should celebrate at Christmas that we may not think about.
In his letter to the Colossians Paul wrote in 1:15-17 that everything was created by Jesus (and for Jesus). If its true that Jesus participated in the creation of the earth, then Jesus is eternal and pre-existent just like God the Father and God the Spirit.
Therefore, for Jesus to come to earth as one of us, he had to leave the beauty, wonder and paradise of heaven behind. He left what was safe, familiar and comfortable to walk among us and use the bathroom like us and feel pain like us and be born just like we are born.
I think it is just as much of a miracle that Jesus chose to leave heaven to be among us as it is that he was conceived in the womb of a virgin. He did it because He loves us. He did it to bring healing and rescue to a world and a people desperately in need of it.
So this Christmas, remember both miracles of the birth of our savior.
