Stern and unforgiving when ones comes upon its limits, though those limits are often misunderstood.
Physics. Logic. Math.
In very simplistic terms, I believe that God exists outside of time and space, and as such is omniscient, omnipresent and omnipowerful. In that context “size” and “shape” have no meaning.
I don’t think God has a “personality”, but chief among His attributes are that God is good, God is love and God is hope - “is” as in none of these things exist outside of His presence. This leads to my belief that hell is not a physical place, per se, but an existance apart from the presence of God and, as a result, apart from anything that could be considered “good” or “love” - a place devoid of any hope.
