He That Eateth of this Bread Shall Live Forever (John 6.58)

Eating my flesh and drinking my blood is metaphorical indicating deep acceptance and relationship. Verse 58 allows for some to be raptured alive and not go through the grave.

"54 Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. 55 For my flesh is meat indeed, and my blood is drink indeed. 56 He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. 57 As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. 58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever" (John 6.54-58).

"25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: 26 And whosoever liveth and believeth in me shall never die. Believest thou this?" (John 11.25,26)

Some who believe in the Lord will never have to pass through death, but shall be raptured alive.
