SimchaMinute by Rabbi Avigdor Miller
When we make Havdala, we should think about the fundamentals of emunah that the creation was made out of nothing, and. also, we should think that the world was made for a nation that would choose to serve Hashem.
This is why He made the world. This is why Shabbas and the election of Am Yisrael go together. We are the purpose of the world. — Youth and Yetzer Hara (#423)
