Jesus said He is the way, the truth, and the life, and no one gets to Heaven without going through Him. That is a radical statement, and can either be accepted or rejected. But do not insult my intelligence or the intelligence of my fellow Christians by saying that all religious faiths are the same.
Poor old Person 1, doesn't get it, does he? Of course not all religions make the exact same claims - if they did, then we'd only have one religion in the world (duh!). The point is that every religion makes similar claims about fantastic things, and all claim to be the one true faith....and I'm sure would feel similarly insulted that a Christian dare say THEY are deluded.
I would suggest that, if you are to reject the claims of Jesus, then you enjoy this life to the fullest. Lie, cheat, steal, do what ever you can to better your position on earth.....Enjoy it now because, when you leave this earth (and all of us will), you will either enter into the non-existence that you believe awaits you, or you will stand before the Creator, and have to give an answer for your life.
I do feel sorry for poor old Person 1, as they seem to have only the very basic arguments to hand. First the deeply flawed "LLL" argument, then the "atheists are bad" hyperbole. Fact is, the vast majority of atheists do what they think is good, because they think its is good. Just like Christians....except Christians also
have the promise of reward.
So I'd ask Person 1, who is the better person? The one who does good and knows they will be rewarded for it? Or the person who does good knowing there is NO reward, no afterlife, and who could gain far more in life by being bad?
And then I'd ask them what kind of a god would punish a person who did good with no expectations, yet reward the ones who creeped along, grubbing about for a reward for the "good" that they did.....
