sorry, just a huge pet peeve of mine...i HATE the distinction of "doctors, cops, etc" being ok to work on sunday but other professions are deemed "less worthy".
it's my role as a provider to provide for my family (see proclamation to family). if i have to do so on sunday then great but no one FORCES a cop or a doctor or an NBA player to work on sunday. they CHOOSE to do so. if working on sunday is not acceptable let someone else who doesn't care be the cop or the doctor.
if it's ok to provide for your family on sunday let's stop drawing our own imaginary, non-doctrinal boundaries as to what type or work is ok on sunday and what is not.
