We godless lack that certainty, and we know the world is a complex place that requires compromise and is not ruled by a moral force - virtue is subject to negotiation, and is found in working together with others to find mutually satisfactory solutions. Good is not absolute, it is an emergent property that arises from successful networks of individuals. It is also something that is measured by evidence: we look at the good that people do, not the promises that they make and never keep, or the lies that dovetail nicely into dogma. Competence is a virtue. Intent is meaningless without action.
