This Shabbos we'll start reading the 3rd book of the Torah, Vayikra. It's opening message teaches: "Adam, A man who will bring from you a sacrifice to G-d".
Technically, this the intro to the laws of sacrifices. One level deeper, the Hebrew for "bring a sacrifice", yakriv, translates literally as "draw close". In other words, this section teaches us how to draw close to G-d.
Judaism uses four different words for humans. Adam refers to the most refined and developed of the four. You could probably say that Adam equates with what we'd call a mentsch.
Step one to draw close to G-d: Make sure that you are a mentsch.
