A proper attitude toward divinity has a very important impact on the way we live. But I will say as to the earlier parts of the article that no prolepsis or anticipation or logical deduction or image or anything else can in my world lead to a divinity which is totally inactive in its own sphere.
I am going to jump in without having read the article, to hypothesize that perhaps the blissfulness (and happiness) of the gods as seen by Epicurus is because he sees them as having perfected prudence, justice, fortitude, and temperance in a manner in which the virtues are used as a tool for happiness...and thus the gods are to be emulated. So that the virtues aren't end, but only the means to the blissfulness.
