God is near you, he is with you, he is inside you... A holy spirit resides within us, an observer of our evil and good deeds, and our guardian. This holy spirit treats us in the same manner as it is treated by us.
Seneca, Epistle 41
That reasoning faculty within us, our mind or soul, that portion of us that makes us rational creatures and separates us from dumb animals, plants, and inanimate objects, is nothing less than a portion of God himself, of the divine reasoning faculty, the very mind and soul of the Cosmos.
When we treat this spirit with the reverence due to the sacred, it guards us from every hardship of live, cultivating Virtue within us and rooting out unnatural Vice. We reverence God, the spirit within us, when we place God not only before all other things, but make this God our only concern.
But when we treat the sacred as the profane, we make ourselves profane. We do so by indulging the body before the soul, by giving way to unnatural desires and passions, by living anything other than a virtuous life and by wanting anything other than what God wants.
If we neglect this holy spirit, it will neglect us. Our reasoning faculty, that divine Reason within us, will be of no help to us against the blows of Fortune or against Fear, Anger, Despair, Intemperance, Ungratefulness, Envy, Lust, Cowardliness, or against any other of the Vices.
This Spirit observes both our evil and good deeds. Observing too often our evil deeds and polluted by them, the reasoning faculty, the God within, having become habituated to Vice is weakened, and no longer has the power to guard us against our own evil or liberate us from sin.
