It’s through God and the faith that He instills in us that He reveals these truth to us. Can I point hell out? Not any more than I can see radiation. But I know radiation exists because of study. I can tell you the principle of radiation. I might see and point out some indications of radiation. I can even caution you against going into a room full of radiation. But you could ask me the same question, “How would my yakking about radiation help you to make sure that radiation really existed?” and off you would go into a room fill with it.
I’ll never convince you in the existence of hell with logic or reason. This type of wisdom is silliness. You will need to ask God if it is so and to lay it upon your heart. I am confident He will do so. If hell really exists, don't you think it's folly not explore all avenues to find out for sure?
