<p>6:53 <i>Jesus replied to them: Truly, truly, I say to you: Except you eat the flesh of the Son of Man and drink his blood, you do not have life in yourselves</i>- There is nothing else of meaning in human experience. His life, as shown in His death, is the only true and lasting sustenance for the believer. As noted on :52, the Lord chose images which He knew would provoke the divide between the literalists, the unspiritual, and those with spiritual discernment. To drink blood was deeply obnoxious to Jews. But unless they would see He referred to His life, and allow that life or spirit to displace their own, then they would have no life in themselves. The life He offers, like the gift of the Spirit, is &quot;in&quot; or 'within' the heart and mind.</p>
