I used to do very technical, complicated work, writing programs to determine overbilling issues and correctly credit people who were overcharged. It was stressful, because a mistake could cost the company I worked for money, potentially large sums of money, the billing system was complex, convoluted really, overbilling could potentially run into the millions, my work was audited, but those audits were limited by the skill of the auditors.
The only way I could sleep at night was to give it my best, use all the skills and knowledge I possessed, work hard, and then stop worrying about it. At the end of the day, if mistakes were made, I would know that I did the best I could, given the limits of my knowledge, skills and abilities and the challenges inherent in the job.
That is how I feel about belief in God. I did my best to look at all available evidence and made a rational decision based on where the evidence led me. I found the evidence for God was lacking. If there is a God, and he judges me unkindly for making the best decision I could make, then he is not a fair and just God, and therefore not actually God, or not a God I could worship.
