Do you see the relationship that our Savior—God with us; the One who never disobeyed God—made with the Passover? It was not with the killing of the animal, but rather with the eating.
These scriptures show very clearly that Jesus and His disciples understood very clearly that keeping the Passover meant eating the Passover. And I think that we can begin to see that eating the Passover might, indeed, be the more important of the two.
