The Torah first introduces us to Noach at the end of parshas Bereishis: “Noach found favor in the eyes of Hashem.” The Chida, citing the Mishnah in Pirkei Avos, notes that when a person finds favor in the eyes of other people (“nocheh” heimenu), this is a sign that he also finds favor in Hashem’s eyes. He also quotes the Zohar which states that the double mention of “Noach Noach” in the opening of the next parshah connotes being “naicha” (pleasant), both above, with Hashem, and below, with people. If the Torah is telling us that Noach found favor in the eyes of Hashem, we already know that he found favor in the eyes of man as well.
Some people are naturally the kind of person that everyone loves. They are pleasant, easy-going, and instinctively know how to interact with all kinds of people. Others have a different kind of nature — they prefer to withdraw from society and instead focus on finding favor in Hashem’s eyes. While that is partially understandable due to innate personality differences, it’s important for us all to know that being liked by others is significant.
Hashem wants us to get along with each other, and as we succeed in finding favor in people’s eyes, we find favor in the eyes of Hashem as well.
