Beginning with the book of Genesis, the lamb has been a very important animal throughout the Bible. The lamb clothed Adam and Eve after they had sinned. The lamb became the chosen sacrifice from Abel for God. The blood of the lamb protected the Israelites in the Passover. The lamb saved Isaac from sacrifice. Many years later, The Lamb was born to save us all from our sins.
Christmas is a time to celebrate His birth. It's a time to reflect on the fact that He came to Earth and was born to die a substitutionary death.
This morning we see that The Lamb was prophesied, was born, and is coming again.
