Sanctifying ourselves is our first and primary Duty.

 Thanks Christianity for near completely obscuring this.

To help others with medicine the first task is obviously to become the best possible nurse or medical doctor. And so it is in every important helping profession. It took Christianity to obscure this with the one and most important thing for every human being to master, you're teaching is an example in the four Gospels. 

Not the putrid diarrhea that came out of Paul's mouth or any of the others. You, the master.
