That sounds like something I can comprehend
Well, I don't know that I totally comprehend it because I don't know how one can not accept the Savior in the hereafter, but I do believe somehow it happens that the chance is given for those who didn't have it here. (Doesn't work for those of us who heard it here.) Another of our teachings warns us that, whatever the state of the interim hereafter where the choice might be given, the same type of spirit that possessed us here possesses us in the hereafter. So it means that those who would have accepted the gospel in this life had they been given the chance will accept it there. But those who wouldn't accept it here won't be different on the other side.
The Lord loves all His children and has not prechosen His saved ones. He has always respected our will, from Adam on down. As C.S. Lewis has said (I'm paraphrasing here), "There are two kinds of people in the end: Those who say to the Lord, 'Thy will be done' or those to whom the Lord says, 'Thy will be done.'" In either event, man's free will is respected.
