Great Discussion! Allow me to throw in these quotes as well:
Philódēmos, On Piety, 1.36.1023 – 1.37.1054: [Obbink] And for the production of benefits from the gods for good people and harms for bad people, they [the kathēgemónes] allow. And for the wise and just it must be conceived that benefits and harms which are no feebler or even greater than people in general suppose are made complete, not out of weakness or because we have need of anything from God, even in return [of] his benefit [here], and these things [the kathēgemónes] say most piously. And in On Gods what kind of source of retribution and preservation for humans through the deity must be accepted he outlines in some detail. And in book 13 he speaks concerning the affinity or alienation which God has for some people.
And of course we all remember SV65 "it is pointless begging from the gods for what one is sufficiently able to obtain for himself."
P.Oxy 2.215, col. 2, lines 8-16 [Chilton] Only be careful that you do not permit any admixture of fear of the gods or of the supposition that in acting as you do you are winning the favour of the gods. For indeed, in the name of Zeus (as men affect to say) what have you to fear in this matter? Do you believe that the gods can do you harm? Is not that, on any showing, to belittle them?
