Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
Whose (or 'He that') eateth my flesh, and drinketh my blood, hath eternal life. This is just the positive expression of what in the former verse He had expressed negatively. There it was 'Unless ye so partake of Me, ye have not life;' here it is, 'Whosoever does so hath life everlasting.'
And I will raise him up at the last day. For the fourth time this is repeated (see John 6:39-40; John 6:44) - showing most clearly that the "eternal life" which such a man "hath" cannot be the same with the future resurrection-life, from which it is carefully distinguished each time, but a life communicated here below immediately on believing (John 3:36; John 5:24-25); but at the same time giving to the resurrection of the body, as that which consummates the redemption of the entire man, a prominence which, in the current theology, it is to be feared, it has seldom had. (See the note at Romans 8:23; and at 1 Corinthians 15:1-58 throughout.)
