Is There a Difference Between Essence and Existence?

A, i like to think in terms of true propositions. There's a real distinction between essence and existence. And then the pay off of the argument is that there's no distinction when it comes to god - there's no disation. A, well, what i wanted to get to thehe question that i had was, s am, thinking about all this in my mind, so bear with me if i'm fumbling around with it.
