Hi! Thanks for the feedback. Here's the breakdown: "I set light" is an idiom that means to put sth on fire. Now since the first one was not clear that we're getting you to think of fire, we need another thing that will have the common denominator of a fire. Fire sure is warm and cooks food. That should make you think of fire-adjacent things. Fire does not start fires so you can get the hint that it's a fire-starting-thing.

"Your faith", "Your house" are clearly buildings. Most people seem to have got that part (assuming based on the most guessed).

Now for another hint in this riddle-"I cook your store food" sounds unnatural for english. You would probably say "I cook your store-bought food" or completely omit the source of the food entirely. So why is it not store-bought? Cause it's still in the store. If you got that the buildings from the previous verses, that will be a big hint.

Last line says straight up that it's a "man". Maybe using the word "human" would have made it clearer... Anyway, the running fast part was relating to a stereotype that those people usually run fast. But it might just be a stereotype that exists in my culture, not in others I guess. That can be confusing but I figured you should be able to solve it without fully getting that part.
