There are things that are around today that are seen as being perfect but as time passes, they will be seen as imperfect. And this is how life has always been and something that will continue to take place.
What this shows is how life doesn’t stand still and that there is always something new or different waiting to be revealed. When something is new or different, it could be seen as better and as the next step.
But while this can be the case, if it wasn’t for what took place before the ‘next step’ arrived, it wouldn’t be able to appear. This shows that it’s not that the previous step or the creation is imperfect; it is that it was just another step.
