The fact of the matter is that some still don't "come unto Me" after it has been give to them of the Father.
What He gave is available to all men.
God isn't picking out who will be converted from darkness and unto light.
Yes, that is exactly what God declares and does: He has picked out those He will save - He is God and it is His prerogative to do so - to save those whom He has chosen, whether you (or anyone) likes it or not.
I'll try this again.
1) no man can come to Jesus unless given to him of the Father
2) ALL those (of #1), WILL COME TO JESUS (with no if, ands, or buts),
3) Of ALL those given to Jesus by the Father, Jesus will neither lose nor cast out any of them.
4) None, besides those given by the Father, can come to Jesus.
Please read these verses closely - they are logically complete and perfect - nothing has been left unaddressed.
[Jhn 6:65 KJV]
65 And he said, Therefore said I unto you, that
no man can come unto me, except it were given unto him of my Father.
[Jhn 6:37 KJV]
37
All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
[Jhn 6:39]
39 And this is the Father's will which hath sent me
, that of
all which he hath given me I should lose nothing, but should raise it up again at the last day. ...
