john 6:58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever. - Free Bible Online

      58. This is that bread, &c.--a sort of summing up of the whole discourse, on which let this one further remark suffice--that as our Lord, instead of softening down His figurative sublimities, or even putting them in naked phraseology, leaves the great truths of His Person and Office, and our participation of Him and it, enshrined for all time in those glorious forms of speech, so when we attempt to strip the truth of these figures, figures though they be, it goes away from us, like water when the vessel is broken, and our wisdom lies in raising our own spirit, and attuning our own ear, to our Lord's chosen modes of expression. (It should be added that although this discourse has nothing to do with the Sacrament of the Supper, the Sacrament has everything to do with it, as the visible embodiment of these figures, and, to the believing partaker, a real, yea, and the most lively and affecting participation of His flesh and blood, and nourishment thereby of the spiritual and eternal life, here below).
