I don't know whether god exists or not. But the fear of god is what keeps many people from doing wrong. I studied in one class that the first laws in this world were made based on morality created from religion. We all know what would happen if there are no laws. Yes, there are the bad people, namely so called religious gurus saying to be the spokesperson for the god, and taking advantage of this. But to the commoners, the god - whatever its name or form be, is required so that there is harmony in the society. The irony is that religions also are the reason that create disharmony, war and violence in the society; but it's not the god, it's us.

God may never exist and might just be the images created in our minds. But it gives me strength, hope, and support, and prevents me from the wrongdoings with the fear that I will be punished. God is what I pray to when I become hopeless and weak; it may all be only in my mind and psychology; but it works as a medicine and guides me to the right path.

It may be god or it might simply be a natural cycle but I believe there is a system that works to punish us for our misdeeds and rewards us for our gooddeeds. We may not see it; we may not know it; it may be very late; but there is something in our nature working something similar to the wheel of karma.

Conclusion: we do need to fear god (don't mistake it for the brand names from the religions or the statements from the so-called religious gurus).
