the Gemara (Brachos 53b) tells us, the one who answers Amen has grater mitzvah than the one who made the bracha. When Habaon RAv chayim Kanievski, shlita, was asked several years ago what we should all be doing in light of the tragedies and suffering Klal Yisrael is going through, Hashem yeracheim, he answered that we have to awaken ourselves and others to do teshuvah, to pray with all our hearts, and to do good deeds.
