What do any tenses have to do with literally eating his flesh and drinkling his blood have to do with it?
OK.... Explain what you see!
For I have no idea what you think you are seeing.
Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man
and drink his blood, you have no life in you. " John 6:53
It is your game.... What are we supposed to do with his flesh and blood if taken plainly as stated?
And, something more accurately translated from the Greek, could read this way...
"Point of doctrine which I {Jesus} keep on saying to you . . .
except {negative 3rd class condition} you eat the flesh
of the Son of Man, and drink His blood - maybe you will,
maybe you will not - you have no {eternal} life in you."
Plainly speaking? How much is a pound of his flesh going for these days?
