We shouldn’t be so superficial in believing. Some carry their parents religion as a noble and dignifying cross. Others are looking for God in strange, intricate concepts and rituals. And some take pride in their freedom of choice, and conclude that there cannot be a higher level of conscience.
The hidden daft truth is that no matter what we believe in, that thing (or lack of it) shapes our own choice of conduct, system of values, our immanent identity. And when we choose to aspire to whatever a two-millennia old con is promoting, or worst, yet, to pure coincidence (hence the nothingness), the chances of reaching some horizon are pretty slim. You will eventually become the best idea you got.
That’s why defining your God is crucial.
