Metaphysical meaning of lamb (rw)
lamb, killed and eaten in the night--Represents the giving up of the animal life propensity in the mortal body. The command is that the lamb shall be without spot or blemish, and be wholly eaten after being roasted with fire. This refers to the complete transmutation and surrender of the human life to Spirit after it has been purified by the fires of regeneration.
Lamb of God--The pure life and substance of Being. By His overcoming Jesus restored to mankind the consciousness of this pure life and substance, which flows into man's consciousness through the spiritual body. Its nature is to vivify with perpetual life all things that it touches. Jesus is called "the Lamb of God" (John 1:29).
