לך לך

Every test that we go through is for our benefit. Rashi wrote when Hashem told Avraham Avinu,לך לך it was להנאתך, לטובתך – it was only for Avraham’s benefit, to bring him good. The Beis Yisrael said one of the benefits Avraham got from this was that Hashem knew; eventually, Avraham would excel in the Mitzvah of Hachnasas Orchim, and now he wanted to prepare him because, during these travels, he would have to be a guest at many different people’s homes.

Hashem wanted Avraham to feel what it’s like to be a guest so that he could deal with his guests in the best possible way. We find so many people who experience challenges in the early part of their lives, and it is only because of those challenges which enable them become so great later on in life.
