Since so many people have been taught incorrectly, I have to repeat myself. There is no such thing as theism except in the abstract. Beliefs are always held by people, for one thing. Furthermore, the word "theism" must be defined before we can know what any particular person means by the word. For all we know, a particular theist could be a polytheist. And although there are a large group of philosophers of religion who have agreed to define the word in extremely minimal terms for discussion, they are discussing "theism" in the abstract too. Hardly anyone defines their beliefs using this minimalist definition of theism, which was adopted in the Occident by Christian dominated philosophy of religion departments, rather than in the Orient by eastern philosophers, or in Comparative Religion departments. No one I ever heard even says "the ONLY things I believe are that God exists, is personal, is omnipresent, omnibenelovent, omniscient, omnipotent, and created the universe. I believe nothing beyond those things." No siree, bob. That person adheres to a much larger religion, guaranteed. Since I think the best way to evaluate a religion is to do so as a whole, when Christians want to talk about theism in the abstract I'll just insist on discussing the evidence for concrete examples, like the reliability and inspiration of the Bible, a Jesus who levitated with Moses and Elijah, a virgin birth, the resurrection of Jesus and his ascension into the sky.
