Charles Spurgeon Commentary John 6:53-54

"Jesus therefore said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man and drink his blood, ye have not life in yourselves. He that eateth my flesh and drinketh my blood hath eternal life: and I will raise him up at the last day." — John 6:53-54 (ASV)

Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.

His soul will live; his spirit will never die; and though his body will die, the force of the eternal life within the man will quicken even his mortal body into an immortality like that of his spirit.
