" heaven is not forever in the way that we think of forever, as a uniform measurement of time, like days and years, marching endlessly into the future. That’s not a category or concept we find in the Bible. This is why a lot of translators choose to translate aion as “eternal.” By this they don’t mean the literal passing of time; they mean transcending time, belonging to another realm altogether. "
