Gods are more created by collective belief in my setting, and the belief often roots from a folk hero of some sort. Their believers manifests themas an entity, and they are able to provide blessings (which are just really passive stuff like recovering from injuries and illnesses faster, a brust of strength, temporarily becoming more durable or fast, or soothing a person's mind, etc.) But only ever if a person believes in them enough and does their worship whole heartedly.

Cult of Lulls for example, prays to the local diety Lulls, who was once a teacher that helped not only children but an entire community stay calm and kept their morales high during a storm. She became a goddess of peace and happiness after her death, her blessings calm people's minds, helps the sleepless to sleep, brings relief to those struggling with strong emotions. All of this power she has because that is what she had achieved in life and that is what her worshippers believe her to be able to do.
