"Misinterpreted"?
I think that it's hard to do that with this:
" And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father." ( John 6:65 ).
No man comes to Christ
unless it is given to that person to do so by the Father ( as we see above ),
and in the behalf of Christ:
" For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake; " ( Philippians 1:29 ).
I'm not sure how much plainer the words could be, sir.
Respectfully, according to John 6:44, it is indeed "effectual", in that God's drawing always results in the person drawn, being raised up:
" No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day."
Here I clearly see that all that come to Christ do so because they were drawn by the Father...
And all that are drawn by the Father will be raised up at the last day.
If
all men were drawn to Him in the "saving sense", as John 12:32 seems to say, then according to John 6:44, they would
all be saved and raised up at the last day.
That is what the language of John 6:44 lays out... a sure and completed ( "effectual" ) drawing and resurrection of those who come to Christ.
In addition, if the drawing in John 6:44 is the same as that found in John 12:32, then Christ is lying when He said that in order for a person to come to Him,
the Father must do the drawing.
Also, Scripture does indeed answer the question of why some people come to Christ when others do not;
Those that come to Him do so
because it was given to them by the Father as John 6:65 states...
While others do not come to Him ( believe on Him, from the heart ) because they are not "of" Christ's sheep:
" But ye believe not, because ye are not of my sheep, as I said unto you.
27 My sheep hear my voice, and I know them, and they follow me: ( John 10:26-27 ).
His sheep ( those that are "of God" ) hear His voice, while others do not ( John 8:43-47 ).
With that, I take my leave of this thread and I wish you well.
May God bless you greatly as you consider His words.
