But with the precious blood of Christ, as of a lamb without blemish and without spot: . . ." (1 Pet. 1:18-19 AV).

Which must have been revealed to John, as he exclaimed early in Jesus' ministry:

The next day John saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world!

John 1:29

So, how do lambs take away (=utterly remove) the abstract “sin” and its effects? I remember reading where lambs were roasted and eaten, right down to the bones.
