Hi David, you have obviously chosen a niche for your website, the theme is basically what your niche is about.
The choice that is available, I am sure there is at least one that could represent your posts on your website.
I wish you well along with the other members who have given encouragement in their responses.

There are so many themes here it's almost overwhelming. I've had good luck with the ones I have chosen.

Your theme is merely the background where you showcase your posts. They will have varying features. How many columns across do you want? One? Two? Three? What kind of features do you want your theme to have? You can preview any of the ones on here and see what they offer.

Surely out of 7400 choices you can find one you like. Look at some of the other websites people are building, and perhaps you will understand a bit better.

Good evening my dear friend, a theme only means what you want your website to be about. You have literally thousands to choose from it helps you to promote whatever you want to promote. May Prosperity be always with you.

Hi - there are 7400 themes offered here, I can't imagine you have looked at them all. Perhaps you are not seeing all the choices? When you log in to WordPress and go to Appearance and Themes, you need to click "add new"
