John 6:53 "So Jesus said to them, 'Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves'."
When Jesus said we must eat His flesh and drink His blood, what was He talking about? How do you know?
(Hint: 1 Corinthians 11:23-32, 1 Corinthians 15:3, 20-24)
