Who do we serve?

Did Jesus differentiate between prisoners imprisoned for murder and those imprisoned for their faith when he instructed his followers to visit those in prison? Did he instruct them to feed only the poor and destitute who are in thier situation through no fault of their own? or only the attractive poor? or the poor who don't smell too bad? What about widows and orphans? All widows and orphans? All the needy? even the really unpleasant needy? or the needy who make us uncomfortable? Are we to seek to find logical reasons to serve? Like helping those with the best chance of survival so our efforts count for more? or those who might be able to repay us someday? Think about it.
