Philo Judaeus De Aeternitate Mundi 46

[46] Therefore, on the same principle, if the heaven is destroyed, the sun and moon will also be destroyed, and all the other planets likewise will be destroyed, and all the fixed stars, and all that host of gods visible to the outward senses which was formerly considered so happy; and to imagine this is nothing else than to fancy the gods themselves in a process of destruction, for this is equivalent to considering men immortal. And yet in a comparison between different objects devoid of honour, if you were to consider the matter, you would find it more consistent with probability to look on men as immortal than to believe that the gods are perishable, since it might happen through the grace of God, for it is not improbable that a mortal might receive immortality, but it is impossible for gods to lose their immortality even if the sophistries of mankind should run on to ever such a degree of wicked insanity.
