There are dozens of videos on YouTube on Hell itself which incidentally it's believed to located below the earths core.
There are many testimonies that people saw Hell by being in it they were shown by Jesus Christ! can they all be wrong?
Satan had no power over Christ in the desert 40 days and 40 nights, even as The Saviour to the earth walked through Hell
Satan is powerless to do anything to Jesus Christ thus making him powerless again and again!
