John 6:37 All that the Father gives me will come to me, and whoever comes to me I will never cast out.
John 6:39 And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. 40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.”
John 6:47 Truly, truly, I say to you, whoever believes has eternal life.
John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life. 64 But there are some of you who do not believe.”
NONE of your citations conflict with this one:
From the KJV: 1 Cor 11:27-29
Wherefore whosoever shall eat this bread and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
But let a man examine himself, and so let him eat of that bread, and drink of that cup.
For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.
What happened to all of your literalism?
