There is no correlation between the duty of man and whether he is blessed or cursed. Duty is what man ought to fulfill; it is his bounden duty and should not depend on recompense, conditions, or reasons. A man who is blessed enjoys goodness upon being made perfect after judgment. A man who is cursed receives punishment when his disposition remains unchanged following chastisement and judgment. As a created being, man ought to fulfill his duty, do what he ought to do, and do what he is able to do, regardless of whether he will be blessed or cursed. This is the very basic condition for one who seeks after God. You should not do your duty only to be blessed, and you should not refuse to act for fear of being cursed. If man is able to do his duty, it is because that is what he ought to do. If man is unable to do his duty, it is because of the rebelliousness of man.
