You will notice three distinct points of view when it comes to the omniscient section. You shall find the third person limited or subjective, the multiple third people limited, as well as the third person omniscient points of view. The third person omniscient point of view takes on an all-seeing type of perspective. It takes into account all angles of observation in the story, with none of the limitations of the other points of view. This gives the author certain advantages.
You will fun it to come naturally as a style of writing. Many of the stories we have always been told, since childhood, were made using the third person omniscient point of view. There was the narrator who went ahead and told the story. This is why many of us naturally lean towards stories told in this style. You wish to read more about the story when you notice this perspective in action.
The author also gets to cover more ground by telling us more about all the characters. The omniscient point of view allows the author inside the minds and perspective of all the characters, thus bringing a deeper sense of understanding to the story. This helps you appreciate why certain characters reacted to something in the story the way they did. You thus shall see the reasons why people had to do the things they did as the story unfolds further.
This style is also the best for carrying the authoritative voice of an author. In the first person point of view, we only get to hear or read the story as if it was one person’s thought and actions that mattered. But this style of storytelling helps the author expand their vision and delivery of the story. You get to retain all the rights to the way the story is told. Your voice is inseparable from the story you are telling.
You also need to adopt this point of view if you are telling an epic story. This works best when your story covers many years, with many characters in it, across vast lands and territories. The same could not have been achieved had you resorted to the other methods of storytelling. You can use those in other forms of writing. If you have a great epic; you now know what method to go for.
You will also get to show the action in a story in a much better way. Since you can take a more distant and higher perspective stance, you can showcase all the actions of your characters. Most action is not limited to one person’s acts. It is therefore hard to tell about it when you can only see through one person’s eyes.
