How do you know that John the Baptist's statement about the Lamb of God refers to sacrifice? (John 1:29). How was the comprehensiveness of "sins of the world" so radical a concept?
Jesus comes to the world, from the high to become like us. Just to bear our sins. you know, just for us, not only the people Father has chosen, for all of us. That's why we are saved.
In His sacrifice, only Lamb of God, Jesus is referred to. nobody else.
Thanks The Lord! Thanks for His love!
