Oops, came across this just a few minutes after I commented. I'd be interested in what you think.

Duty is a subterfuge of vanity.
  
There are no shoulds in the kingdom of heaven, and that is where we are to reside in each moment...the everlasting Now.  Any moral or ethical demands we hold and act from in response to our neighbor, is not the Father doing the works; it is our understanding, effort, and judgment, for which we claim achievement.
