Is God a Part of His Essence?

Every negative thing that we have to say about god, it should be pared with something that is positively stated. I think ain thinkers, like augustine aquinas the reform orthodox, and all of them, inside, or in connection with each of the negative points that they make, there is positive content. For example, a impassibility is not merely about negating that god has passions like human passions. It also goes with the emphasis that god's goodness is entirely sufficient for himself,. He fully delights in himself eternally and and in the fellowship of father, son and holy spirit.
