Dear Lorgar, you have a very promising thread because you want to know in effect how to prove to yourself God exists.
My observation is that with atheists they don't want to know at all how to prove God exists, they just keep on and on with the declaration that there is no evidence, period - that is a sensible position, though.
But what is not sensible is that they will at all never want to talk about what is evidence, what is the the target of evidence, and how does evidence hit its target.
I am very excited to work with you so that you will come to the certainty that God exists.
First, tell me if you care at all, what do you think is the best argument from atheists that God does not exist/
I assume that you have read arguments socalled, from atheists on why there is no God.
If you tell me that you don't know any at all, and that is why you want to know how to prove to yourself Gold exists, very good: at least you want to know.
Okay, here goes, how to prove to yourself God exists:
1. Do you at all have any concept of God?
You know, if you don't have any concept of God at all, then and bear with me, you are being irrational i.e. unreasonable to ask how to prove to yourself God exists; why you irrational?
Simple, because as you don't have any concept of God at all, you will not know He is present to you, even though He is just beside you or even all over you inside and outside.
Take this illustration: If you don't know what is a woman, even though one is facing you all naked like an infant just born, totally naked, and you are not blind, will you know that it is a woman facing you - I assume you are a guy, i.e. male.
So, in just 50 words or less, tell me what is your concept of God if you have one at all, even how crude.
You see, I intend to guide you step by step to come to the certainty that God exists, so if you cooperate you will certainly come to the truth, the fact, and the logic that God exists.
Don't run away now.
