You are smart, you have told us that. How would it hurt you if you were not making as much as another person in the same job? A bit of a hint, what could that person do that you could not because of money?
Would you feel it is unfair that you were being paid less for doing the same job as well or better?
Think about it. I am sure you can figure it our on your own.
If this is your answer ( still doesn't answer the questions though) then you are ignoring this same Paul's command to BE CONTENT in whatever situation you find yourself.
YOUR philosophy condemns the guy (as told by Jesus) who hired men all through the day but paid each the same at the end of the day. And you do know what Jesus said about the complainers, do you not??????!!!!!!!
One facet is common with the progressive/liberal/demoncrat philosophy; it consistently picks only those beliefs that support non-sensical, irrational & failed policies.
