It's not a threat just a statement and we all will eventually find out.
Of course it's a threat. Your underlying message is repent now or burn forever in a lake of fire.
You say it's just a "statement", great, provide good evidence for it.
Additionally your claim "we all will eventually find out" is also unsupported. If you are dead, and there's no existence after death, you will not exist in a state capable of experience, so no, you won't find out....
Where is (good) evidence there is no existence after death?
Where is your (good) evidence you will not exist in a state capable of experience?
Where is your evidence that you won’t find out?
If you claim God doesn’t exist, you bear the burden of proof. Your evidence for atheism is missing. I have yet to see scientific evidence that God doesn’t exist.
Your convince-me scientific mindset is growing wearisome...
