You god is too small if your god…
…gave you dominion over all other creatures;
…revealed itself only to a special few;
…is white, black, or any other race;
…sanctions barbarism of any kind against other sentient beings;
…cares about your sexuality;
…authored its own holy book;
…gets offended;
…has chosen people;
…is a jealous god; or,
…supports your country, political party, religion, or opinion over any others.
Excellent!
