There is a line of reasoning that says "If the atheists are correct...and after death...we all disappear into nothingness, then the Christian believers have lost nothing. But if Jesus is real...and after death...eternal life truly does begin, then the atheists are in a lot of trouble.”
That said...regardless of the hereafter...many will attest that the life that people live, here and now, is made more fulfilling, and 'easier', when one walks through it being a fully devoted follower of Jesus...and having a one on one relationship with Him.
That's called Pascals wager, which I've already debunked earlier on this thread. At the very least Christians do loose something if there is no God. They lost 10% of their wages, and didn't get to sleep in on Sunday.
Some believe that Atheists...along with those who are not disciples of Jesus...will likely lose a whole lot more than 'that' if and when they find out that there is a God...and there is a Jesus...and what He said about Himselff is true.
And what do you loose if you get the the pearly gates and you are greeted by Joseph Smith, or Muhammad, or one of the other thousands of gods that have existed?
As you can see, Pascals Wager is also a false dichotomy wrapped in a threat.
we're steadily narrowing down the numbers though. the Greeks had about 100 until the successful input of the early Xtians reduced it down to 3. that's quite an accomplishment right there, I'm sure you will agree.
