I agree Don, I think both blessedness (i.e., contentment) and indestructibility are necessary qualities of gods. These qualities serve as examples for us -- but our limits in both regards are fully acknowledged, per Philódēmos:
"…the intimacy arising from necessities, in regards to association, gives the emotions over to [that intimacy]: for maintaining intimacy, while existing [together], is not possible without any mixture [of emotions]. Indeed, certainly for us, who are weak and have further need for the necessary things of friendship…"
…χρειωδῶν ἡ συμφυλία π[ρὸς τὴν] συνανα[σ]τροφὴν αὐτῆι τὰ πάθη παρ[αδί]δωσιν. οὐ γὰρ δυνατὸν ἔχειν τὴν συμφυλίαν ἄνε[υ] πάσης ἐπιμειξίας ὄντας. ἀμέλει δὲ κ(αὶ) ἐφ' ἡ̣μῶν τῶν ἀ̣σθενῶν κ(αὶ) πρ(οσ)δεγομένων πρ[ὸς τ]ὰ [χρ]ε̣ι̣ώδη τ[ῆς] φιλίας
Philodemus, On The Gods, Book 3, P.Herc. 152, fr. 9 (87)
Philódēmos directly connects human weakness with our need for friendship. While discussing the importance of mutual friendship / intimacy (ἡ συμφυλία) he says that generosity is necessary.
