None of us know the answer to the coronavirus domino question, although it has been pointed out on another thread about how viruses have been involved in making the human genome what it is today.
One musing on why God might have created the currently imperfect universe instead of the future perfect heaven was already mentioned further up in this thread.
Michelle:
Clearly, we are not already in heaven, because there are so many things wrong with our current world. At least this way we will be able to appreciate the difference between what it is like to live fully according to God’s will (in heaven), versus what it is like to live when we are usually selfish (in our current life), so we’ll appreciate heaven more when we get there.
