Hey Rhys,
This is a tough topic that doesn't have a clear cut answer everyone will be satisfied with.
Ray specifically said they will incur a punishment that will apparently be a surprise, even to us.
Maybe this will help you find the answer you're searching for re what punishment certain people will receive:
Luke 12
41 Peter said to him, "Lord, are you telling this parable to us, or to everybody?"
42 The Lord said, "Who then is the faithful and wise steward, whom his lord will set over his household, to give them their portion of food at the right times?
43 Blessed is that servant whom his lord will find doing so when he comes.
44 Truly I tell you, that he will set him over all that he has.
45 But if that servant says in his heart, 'My lord delays his coming,' and begins to beat the menservants and the maidservants, and to eat and drink, and to be drunken,
46 then the lord of that servant will come in a day when he isn't expecting him, and in an hour that he doesn't know, and will cut him in two, and place his portion with the unfaithful.
47 That servant, who knew his lord's will, and didn't prepare, nor do what he wanted, will be beaten with many stripes,
48 but he who didn't know, and did things worthy of stripes, will be beaten with few stripes. To whoever much is given, of him will much be required; and to whom much was entrusted, of him more will be asked.
2 Timothy 3
1 But know this, that in the last days, grievous times will come.
2 For men will be lovers of self, lovers of money, boastful, arrogant, blasphemers, disobedient to parents, unthankful, unholy,
3 without natural affection, unforgiving, slanderers, without self-control, fierce, no lovers of good,
4 traitors, headstrong, conceited, lovers of pleasure rather than lovers of God;
5 holding a form of godliness, but having denied its power. Turn away from these, also.
6 For some of these are people who creep into houses, and take captive gullible women loaded down with sins, led away by various lusts,
7 always learning, and never able to come to the knowledge of the truth.
8 Even as Jannes and Jambres opposed Moses, so do these also oppose the truth; men corrupted in mind, who concerning the faith, are rejected.
9 But they will proceed no further. For their folly will be evident to all men, as theirs also came to be.
There is no denying that a few truly don't know what they're teaching is wrong and blasphemous and NOT the Lord's will.
But there are many who definitely know the difference between right and wrong. They will be tormented in the presence of the Lamb. (Ref. Rev. 14)
Someone remarked, a lamb couldn't possibly torment anyone. True, but when God opens your eyes and you see yourself in the Light of Christ's Goodness (as Paul saw himself)...it's humbling to say the least -- it's akin to mental torture. (Oh my God I can't believe I did that. - You know what I'm saying -- we've all said that ourselves over stupid childish stuff we've done and we know that feeling.)
They will be saved in the end, sure. But if they do not examine their words, and repent now in this life, they will not reign with Christ; they will have received their rewards here on earth.
Hey, wherever your treasure is, there will your heart be also. We must be willing to forsake ALL! It's not good enough to give to charity and do good deeds, though that's not a bad thing, but get a load of this: Even the Mafia, etc., does good things for their own.
