Q. when we say that saying something over in someone’s name brings geula laolam, how come that after so many thousands of years of repeating the words of our sages, the geula has not yet come?

A. Maharal (Avos 6,6) elucidates this aphorism saying, that when the Geula does eventually come, it will come to pass by someone who observes and keeps this principle. (Rosh Eliahu p.33)

Horav Shlomo Miller Shlit’a explained, that there is a universal Geula and a individual or partial redemption. Giving due credit to an author, brings about only partial or individual deliverance, as it was the case with Mordechai and Esther. (Megilah 15a, see also Chasidim Mesaprim p. 195, in the name of the Choize of Lublin).
