The worldly perks of inferior definitions of "God" are many, and both some atheists as well as some theists maintain those inferior definitions.
Taking pride in one's intellectual prowess for having figured out on one's own which religion is the right one or what the truth about God is;
expecting or demanding from other people to give one special respect for being a member of the right religion or for having figured out the truth about God on one's own;
taking pride in one's social, cultural, national, racial, economic background as being decisive for one's membership in the right religion;
deeming oneself better than other people;
- these worldly perks are possible only for someone who operates out of an inferior definition of "God".
In the proper omnimax definition of "God," where "God" is defined as the First Cause, the Creator, Maintainer and Controller of the Universe, so, as far as definitions go, God contextualizes everything that happens in this Universe.
With such a definition of "God," a person considers that their every breath, their every bowel movement, every thought they have, everything they feel, think, say and do, is contextualized by God.
Such a person has no basis to take pride in their intellectual prowess (for they know it is provided by God), cannot demand special respect from others (as they know that everyone is just as much part of God as they are), knows that one cannot take credit for one's social, cultural, national, racial, economic background (as they know it is provided by God), and cannot deem themselves as better than others (as they know that nothing happens without God's will).
