The opening of this shiur, in Rabbi Dovid Orlofsky’s own words — taken from the captions, so names and Hebrew terms may be approximate.

Hi, this is Dov Laski with the question and answer series. >> [music] >> And somebody writes in, "If time travel were invented tomorrow, would that be a good thing or a bad thing?" That's an easy one. Somebody asked me, "What happens if you die and you get up to heaven and you see Jesus is waiting for you?" I said, "Then I know I went the wrong way. That's all. You have to turn around." >> [laughter] >> He said, "But how are you sure?" I'm sure. Trust me, I wouldn't be doing this if I didn't think that I was right. I was once challenged by a reformed student on campus. He goes, "So, you think you're the only one who's right?" I said, "Of course, I wouldn't be doing this if I didn't think I was right." Jews did not give up their life for centuries thinking that maybe they were wrong. That would work out really awkward. And so, even though the Christians believe that all of us non-believers are going to be tossed into the pit of hell and burnt in eternal damnation fire, I'm not really worried. I'm I'm I'm pretty secure I'm going the right way. Yeah.
