Ian Jackson preaches on the only two occasions in scripture that the head, legs and inwards of the animal were put together in one place. In Exodus 12, the lamb in all it's parts was put on a table- a whole Christ on the table to feed upon. In Leviticus 1, all parts of the animal were put together on the altar- a whole Christ on the altar in worship. Ian stresses the need to daily feed upon a whole Christ- his mind (head), walk (legs) and affections (inwards).
