But if one does not want Christ as Lord, it evidences that want sin (including idolatry) over Him, and would not like Heaven either.
And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. (John 3:19-21)
So why have billions of Hindus chosen darkness over light for the last 2000 years? Are they all going to end up in the lake of fire?
That depends on how one defines sin, does it not? For that matter, does a Buddhist monk (as one who most evidently does not want Christ as Lord) want sin and idolatry?
As for Heaven, it's a place in which I have no belief that it exists, so the point is largely meaningless (to me, anyway). You might as well be saying that I wouldn't like Middle Earth or Narnia.
