In the fulness of time it pleased God to send His Son upon this earth. As the Saviour he would need to be very man and truly God. To fulfill the prophecies he would be born of a virgin and be conceived of the Holy Ghost. Therefore He is also called Immanuel, which means God with us. “For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life.”
The humble birth of Christ is a wonder, but another wonder needs to take place. By grace the Lord needs to make room in our hearts that Christ may be born in our hearts and then we may also hear with the shepherds that “unto you is born this day a Saviour.”
