Good point. But for me there is a big difference between a lemon and God. Many have seen a lemon and know what the word is referring to. Nobody or maybe few have seen God but many use the word. So the relationship between God and the word “God” must be different than that between lemon and the word “lemon”. As far as I understand, there is no “actual God” (like “actual lemon”) because God could be thought of as the creator of Actuality.

John 1:1 is kind of at the heart of that, explains how god comes about with words, ideas.
