How is a third-person omniscient narrator used in a story?

The third-person omniscient is a type of narration in which the narrator has access to the personal thoughts and feelings of all the characters. This is often compared to the perspective that God would have, as the narrator is able to see everything and know everything, even the things that the characters do not state. An easy way to identify whether this is being used in a sentence is by paying attention to whether the narrator is able to get inside the mind of more than one character.

should you be the one doing this journal entry? it says "your special talent or skill". are you gonna lie 'bout your talent and make us fake a talent for you?

also this is a really easy journal entry, you can just think of a skill your good at and write did you work hard to become good at this skill (ex: drawing, writing, math, playing music, etc.) or does it come naturally (like a cool trick that you can do with your body). you can do all of that in 150 words. just try and think of a talent and even if your bad at this talent just say your working hard to become good at it.
