In John 6, Jesus teaches that eternal life requires eating His flesh and drinking His blood, a shocking concept to many disciples who struggle with the prohibition against consuming blood. Speaking metaphorically, He refers to partaking in bread and wine as symbolic of His body and blood, a profound act before God. Many turn away, unable to understand, while Jesus remains untroubled, asking the Twelve if they will also leave. His blood, shed nearly two thousand years ago as the ultimate sacrifice, holds unmatched power to atone for sin. Only those drawn by the Father can come to Christ, showing His blood is for the elect called by God. Also see sermons and articles about 'Jesus Christ's Blood, Drinking'.
John 6:53-56 Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed, and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him.
