But surely 'it' would make more sense in that case.
When you put it like that, Trent, I suppose it does. However, calling God "It" irks many people, they feel it is said, not to be precise but to be disrespectful. It's unkind to use terms that hurt people when there is no good reason for it.
It (no pun) doesn't bother me now, I vaguely remember it did some time ago but not now. So there's no reason why someone doesn't say (or write), "god" with a small g, or "the deity".
However what you say does make sense so I will not criticise the use of "It" now.
I reiterate what I said previously, God is a spirit and has no gender so, strictly speaking, no reason why he/she/it cannot be called "She",
in my opinion. If someone comes up with a reason not to I'm prepared to listen. I use masculine terms for God because I'm used to doing so, Jesus did (for reasons already given), and I like the "father figure"; however, "mother figure" is equally as important. Some non-Christian religions seriously revere a mother god and no-one finds that odd.
