P18: No one can hate God/Nature.

Dem.: The idea of God/Nature which is in us is adequate and perfect (by IIP46, P47). So insofar as we consider God/Nature, we act (by IIIP3). Consequently (by IIIP59), there can be no Sadness accompanied by the idea of God/Nature, i.e. (by Def. Aff. VII), no one can hate God/Nature, q.e.d.

Cor.: Love toward God/Nature cannot be turned into hate.

Schol.: But, it can be objected, while we understand God/Nature to be the cause of all things, we thereby consider God/Nature to be the cause of Sadness. To this I reply that insofar as we understand the causes of Sadness, it ceases (by P3) to be a passion, i.e. (by IIIP59), to that extent it ceases to be Sadness. And so, insofar as we understand God/Nature to be the cause of Sadness, we rejoice.
