When someone believes in another person, it can change the trajectory of their life. Ordinarily that person may not have mounted to anything special and because someone believed in them they became extraordinary. It can be a parent, mentor, a friend or someone else who believed in them.
The pasuk says, וַיְהִי אֹמֵן אֶת הֲדַפָּה he had reared Hadassah who is Esther.1 Now, Esther had neither a father nor a mother, so how did she manage to accomplish extraordinarily with her life?
The word אמן hints to the secret behind her success. אמן is related to the word אֱמוּנָה. Mordechai believed in her. He looked beyond her difficult background and circumstances and conveyed a powerful message: "Your past does not determine your future. You can accomplish great things.”
Sometimes, the greatest gift we can give another person is simply to believe in them-to see their potential even when they cannot yet see themselves.
1 Esther 2:7.
