Q. In Zochrenu LaChayyim, why do we ask God, “Remember us for life… for Your sake”?
The Chafetz Chayyim gives two answers. One compares us to a customer who tells his supplier, “I am buying for your sake as well as mine, because without customers you cannot continue in business”. In this sense God is like a king who cannot be called a ruler unless he has subjects.
The second answer given by the Chafetz Chayyim is, “‘For Your sake’: so that we may be enabled to serve You properly.”
