Well, thanks for asking. I have kind of a different take on that verse and John 3:16 too than most do. I posted it some time
ago but it wasn't really recognized, however, for me, in viewing it in this way, it seems to reconcile everything pretty well.
Now don't laugh when I say it, (lol that means you Cameron143), but I believe there are two worlds in view: 1) this current world which is to be destroyed, and 2) the world to come which will be eternal, and is, as I understand it, to be comprised of the saved.
Were it not so, it would mean that either God can't destroy that which He hates nor save that which He loves.
The world in 1John 2:2 and John 3:16, is the world to come, not this current world. That is the world which Jesus saved by
the forgiveness of sin.
I've found generally that the Bible can use the same name for the earthly for the spiritual, so this is where the "no verse of
prophecy is of any private interpretation" and "comparing the spiritual with the spiritual" comes it to play to determine
which one is in view. Okay, you can laugh now, Cameron143.
Hope this helps
