Help me refute the "suffering will be insignificant in heaven" theodicy

[Sheldon]

Hi guy, I am making a video refuting some responses to the problem of evil, and I would like some help refuting a response. The response is that the suffering human beings endure on earth will be insignificant when we are in heaven, and it will almost look just like a bad dream. What would you guys say to that?

 It's probably better to get an in-depth knowledge of what Christians say before doing a refutation.

Or one could simply ask if they can demonstrate in any remotely objective way, that what they are claiming is possible. If not then one need refute nothing, just treat the claim as one would if they claimed they owned an invisible dragon, or any other unfalsifiable claim. The fact a claim is made by someone of obvious intellect, does not on its own lend the claim any credence, this is a form of appeal to authority fallacy.

Not believing a claim, is not the same as refuting it, and thus need carry no epistemological burden of proof, to suggest otherwise would be to invoke an argumentum ad ignorantiam fallacy. I remain agnostic about all unfalsifiable claims, as I must, and withhold belief from them all, as I must.
