Sacrifice. Scripture, reflection and prayer.

John 1:29-34 "The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world! This is the one I meant when I said, ‘A man who comes after me has surpassed me because he was before me.’ I myself did not know him, but the reason I came baptizing with water was that he might be revealed to Israel.”Then John gave this testimony: “I saw the Spirit come down from heaven as a dove and remain on him. And I myself did not know him, but the one who sent me to baptize with water told me, ‘The man on whom you see the Spirit come down and remain is the one who will baptize with the Holy Spirit.’ I have seen and I testify that this is God’s Chosen One.”
Reflection. 
"Look, the Lamb of God, who takes away the sin of the world!" As we draw nearer and nearer to the rightful celebration of the birth of Jesus, it is well worth reminding ourselves that Jesus came and dwelt among us with a purpose.  
"Look, the Lamb of God, who takes away the sin of the world!" He did not come just to get to know what it means to be human. He came with our salvation in His heart. 
"Look, the Lamb of God, who takes away the sin of the world!" When you gaze in wonder at the crib, please look again. 
"Look, the Lamb of God, who takes away the sin of the world!" This is Love incarnated.
Prayer. Thank you, Lord Jesus. Amen.
