Attacking? I wasn't attacking. I was trying to help you express yourself in a way we could all understand.
I said that conventional Christians believe that you do not need a proof that God exists to believe that God exists. I do not know if you are purposely attacking a strawman, or are simply confused.
I was only trying to help you see your own confusion, and the confusion you were in danger of creating in others by not defining your own terms. But let me now take you at face value, and answer your question.
If, by "do not need a
proof" you mean to define that term as listed in my last message above, i.e. a mathematical-type 100% proof? If so, your question itself is nonsense. For then no one has "proof" for anything at all. Even science then has none, for science is empirical, ultimately pertaining to the real world, not mathematical and merely formal in its conclusions. So that question cannot be answered at all. "Proof" is for maths.
If one does not have faith in Jesus
By "faith," are you sticking to the definition? Then your question translates to, "If you refuse to consider the evidence for Jesus Christ and prefer to go to God on your own terms, will you end up alone, separated from God forever?"
If that's your question, I can answer it for you.
The Biblical answer is clearly "Yes."
"Neither is there salvation in any other, for there is no other Name under Heaven that has been given to men whereby we must be saved." (Acts 4:12)
That's pretty plain, isn't it?
