This is a subject that has rattled around in my mind on a few occasions. The Watchtower’s paradise paradigm does create certain dilemmas and contradictions in my mind.
For example, a society that is devoid of problems or conflict will also be a society that is completely comfortable; and therefore a society which has no need for expressions of empathy or compassion. Compassion and empathy are expressed toward one’s fellows because of their state of grappling with some form of pain, discomfort, or conflict. So, how would humans express their God-given attributes of compassion and empathy in a world which evokes none? How would humans manifest their God-given attributes of mercy if there was no sin committed against them?
Another issue: If events such as earthquakes and large volcanic eruptions are considered disasters, why did God place humans upon an earth that is intrinsically designed to shift, move, and evolve in the ways that it does? Furthermore, will God suspend all of these phenomena in the New System as to prevent earthquakes from destroying people’s houses? If so, why did he bother to design the earth to shift in the way it does?
