Theism is a belief in a higher being or god. It means that you believe there is something bigger than us in the universe, and this being is responsible for making and controlling everything. This being is often referred to as a god and is seen as a loving and kind force. People who believe in theism often follow a certain religion or set of rules based on their view of this god. They often pray to their god and look to the god to help and guide them in their life.
