I am an atheist, I have no struggle against my non belief in god.
In fact I have an inner contentment because I don't believe in god.
It gives me satisfaction and happiness that I brought up my family to think independently, none of my children (three) believe in god and have shown me they are thankfull that they did not have an upbringing which which included bowing the knee to an unseen supernatural deity.
Believers imo base their knowledge of theism on ancient hearsay and disputable uncorroborated myth from far less knowledgeable people.
They take their courage from the belief that faith is certain when in fact it can only be the exact opposite.
Their intellectual honesty they are prepared to cede because of fear.
