God can tell you what to do. But not directly. It is either through some holy books, or some prophet, or some guru. So the believers follow this path. They believe, hence they are called believers.
But there are some who don’t go by the reasoning of holy books, prophets, or gurus. It does not appeal to their reason. They find it illogical. They sometimes call it superstitious. So what do such people do ?
They listen to their own intellect, & reasoning. They weigh the issues scientifically. They don’t accept non-scientific answers. They listen to their common sense.
Common sense is my god !
