This biblical passagec -- the specific teaching of Jesus on the issue of freedom after death, especially as concerns "hell" -- would seem to entirely refute your current position:
Luke 16:19-31 (ESV) "There was a rich man who was clothed in purple and fine linen and who feasted sumptuously every day. 20 And at his gate was laid a poor man named Lazarus, covered with sores, 21 who desired to be fed with what fell from the rich man's table. Moreover, even the dogs came and licked his sores. 22 The poor man died and was carried by the angels to Abraham's side. The rich man also died and was buried,
23 and in Hades, being in torment, he lifted up his eyes and saw Abraham far off and Lazarus at his side. 24 And he called out, 'Father Abraham, have mercy on me, and send Lazarus to dip the end of his finger in water and cool my tongue, for I am in anguish in this flame.' 25 But Abraham said, 'Child, remember that you in your lifetime received your good things, and Lazarus in like manner bad things; but now he is comforted here, and you are in anguish. 26 And besides all this, between us and you a great chasm has been fixed, in order that those who would pass from here to you may not be able, and none may cross from there to us.'
27 And he said, 'Then I beg you, father, to send him to my father's house-- 28 for I have five brothers--so that he may warn them, lest they also come into this place of torment.' 29 But Abraham said, 'They have Moses and the Prophets; let them hear them.' 30 And he said, 'No, father Abraham, but if someone goes to them from the dead, they will repent.' 31 He said to him, 'If they do not hear Moses and the Prophets, neither will they be convinced if someone should rise from the dead.'"
Why, after realizing the error of his ways, and KNOWING AT THAT POINT FOR CERTAIN that a better existence was available at ths side of God, whom he could evidently see, did he not simply exercise his freedom of will and cross that divide, repent and turn to God? He seemingly GREATLY desired for that to happen, or at least just one ounce of mercy be extended his way, and when denied that, his next great desire was that no one else would suffer the same fate as he. But, alas, he actually had NO CHOICE in the matter, and neither would Christ send a special messenger apart from the WORD OF GOD ALREADY SENT to warn others whom this rich man loved of what was coming their way.
At this juncture, you either recant of your heterodox belief in after-life free will or admit that you are not in fact following what the Scriptures teach on the subject.
And, PLEASE note... I am not saying this to be mean-spirited -- not at all -- I am giving you the warning that the rich man in this story greatly desired to be given to his family. I am showing you IN THE WORD OF GOD that you are in error, not because of what I believe, but because of WHAT IS WRITTEN.
Don't end up sitting next to the rich man and wishing that things could be different, for they will be what they will be and you will have no choice in the matter.
