nishtdayngesheft: “I suspect the OP question was referring to acting as a real Jew.”
Gavra at work: “You may want to re-phrase your question as an “Oved Hashem”, not a “Jew”.”
If the OP meant either of the above (which it sounds like it from her answer), then all of the following are correct:
Shopping: “live your life only for Hashem.”
MA: “to focus on serving Hashem 24-7 in whichever way is best for you”
Gavra at work: “An Oved Hashem is someone who asks consistently “What does Hashem want from me now”, and is willing to defy common society to do what the RBSO wants from them.”
That is how the Rambam defines an Eved Hashem – as someone whose entire purpose in life is to serve Hashem and EVERYTHING he does is for that purpose. This is a chiyuv and not a chumra.
Beautiful answers everyone, and may we all be zoche to be true Ovdei Hashem in whatever we do (even we are posting in the CR).
