I have been wondering. It seems that so much of what defines our “personality” is really just the measure of virtue or vice we have, or our views on the world, or what our interests are (some of which can be bad). Someone may be a nice person, who has the virtue of kindess. Someone else a hot-tempered person, who is prone to the sin of wrath. Someone else a shy person who ideally would learn to come out of their shell. Or someone is quite the hippie-druggy-new age kind of person… But in heaven where all are perfect, what differentiates them anymore? Surely not only one “type” of person is in heaven? What are those legitimate differences that make our personality?
I think the animal kingdom is actually a good example to draw from. We see whales, crabs, manta rays, sharks, otter, penguins, seals, seagulls, wolves, deer, bears, lions, raccoons, prairie dogs, porcupines, foxes, snakes, iguanas, turtles, frogs, salamanders, cats, dogs, eagles, hummingbirds, and so the list goes on. They all have different personalities and attributes which make them part of the cosmos of creation, and reflect some unique facet of the infinite beauty of God. A wolf shows ferocity. A penguin shows endurance. A snake shows shrewdness. An eagle shows splendor. A hummingbird shows swiftness. All of these earthly creatures of God are signs of divine truths.
If we were to pretend these creatures all possessed rational souls as human beings do, a penguin would strive towards holiness, and a turtle would strive towards holiness, and an eagle would strive towards holiness, and this holiness would all be recognizable by each of them, and yet in “becoming perfect” an eagle would not cease to be an eagle, but rather, would become a more perfect version of itself.
