I say "looking forward to it" or usually when they tell me im going to hell "ive got a 1st class ticket, wanna come?" or my favorite, "well I guess I better make it worth it then"
also I point out any number of things that are equivalent in there gods eyes to my minor offence

My usual response is, "I'll save you a seat by the fire" , and then walk away.

I kill them and eat them, metaphorically of course, or alligatorly if I happen to be in Florida.

Tell them hevean is in your mind

When threatened with Hell, I reply "I hope so.... Ever heard of fuck in heaven?"

I'd rather be in hell than in heaven with religious people.

I roll my eyes - "thank you for your input"

Laughter!

If I don’t brow beat you with my pagan ways then back up and start over. Respect is key if I didn’t invite you into my space then you need to know your place ????

I say 'thank you'

I like to point out to them that if their god wants me to be saved from the bad place he made for me, he simply has to show me the exact right thing to make me a believer and follower. If this god made everything then it gave me too skeptical and intelligent a mind to believe in any unproven deity.

Oooga booga

Hell doesn't scare me. YOU do, but Hell doesn't.

Sometimes something inside of me take over and looking them straight up and I say... "You are the 4th person today telling me that. How do I know you are not lying? You know, you are lying to me. Whatever their response... And you lying again. There you go lying to me again. You are the 4th person today to tell me that lie. Why you are lying? Who is telling you to lie to me. Why you lie."

Next time i will say cool are you giving the punishment and do you also like too receive them, i usually say that i do beileve in such places have hell or heaven but i do beileve some souls get trapped sometimes between worlds, im not organized religion friendly

Laughter, usually.

I think it's funny, I don't believe in those things.

Ask them why they think anyone would want to spend eternity with someone like them. That usually quiets them down.

I laugh at them & tell them that their ridiculous delusions have no affect on life (or after life, for that matter).

I get all choked up and say "I'm Sooooooo scared"

That has never happened to me. Ever.

Laugh.
Maybe say, well all my friends will be there, if they tell me I am going to Hell.

I say " you wanna get butt naked and wrestle?"

I tell them, “Sorry, Satan already offered me a job in Human Resources!” “Now run along, I’ll see you later.” With a devious smile.

I would just laugh at them and tell them you will be sent to the North Pole because I would rather be hot than cold.
