I used to see God in my life all the time. I would be overcome by feelings of peace and comfort, and I would know that was him. Coincidences would come together for my benefit, and I saw that as him protecting me. I would contemplate nature or look at a beautiful natural view, and my heart would swell with appreciation and I would feel humble.
I no longer believe in a god. But you know what---I still have all those things! Sometimes things just line up perfectly. Sometimes I just find peace and comfort within myself. Looking at stunning sites still fills my heart with appreciation. It's no different at all. I just don't credit a god with those things.
So I must conclude that none of these things that I attributed to a god were actually a god. Because they have not changed. Amazing coincidences still come together, and I know longer pray. I see no real difference in my life as I see in those that look for a god. We both have our ups and downs and they are no better off.
