Living in a state of sin? Absolutely. Fully corrupt and depraved? Certainly not everyone, yet still separated from God because of sin.
Living without God in this life will have you exist without God in eternity.
Still, as far as today and the rest of the days in your life are concerned you can do whatever ya wanna.
I'm not going to go into a debate about religion, as it's well outside my genuine interests.
Concerning the following:
"Living without god [...] without god in eternity".
That's quite the statement to make. When you are neither God, nor has the existence of such an entity being confirmed or authenticated.
This, combined with your last sentence makes you come off as a smug know it all.
Which is fine, you can do whatever ya wanna.
