God instituted circumcision specifically "for tradition's sake" - it was to be a sign of Abraham's covenant with God. Someone needs to actually read his Torah.
>>”God, he concluded, wouldnt be impressed by the desire to do something simply for traditions sake.<<
I heard a Rabbi on the radio one time give a great argument. he said “everyone asks me why we keep Kosher when clearly the rules were health rules and are not needed today? My answer is: Because My God told me to.”
So the answer is yes, God wants you to do it because He commanded it.
