Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.

“eats” = trogo. Jesus uses a different word for eat than He used before. This one means to crunch or eat noisily, as an animal feeds, or a man crunches on fresh vegetables or nuts. There is the notion of enjoyment that goes with this verb. The tense is present, not the once-and-for-all aorist tense of the preceding verse.
