We have no idea how to even think or speak of God's world or worlds beyond our own.
"It just IS" is a statement of unbelievable arrogance (apologies).
If a man blind from birth cannot comprehend what it is to see, how can we comprehend anything beyond that perceived by our senses and our tiny, self-consumed minds?
Whatever eternity (i.e. God's world) is...is so incredibly beyond our capacity to imagine that all we can do is express humility at the prospects of touching just a fleeting corner of it.
Eternity? Oh, pish-tosh. I experienced eternity
before I was born, and there was nothing to it.
OK, you post something about God being bored and drinking coffee deciding, on a whim, to create creation sitting on His “back porch”, and you tell me I’m arrogant?
I’m not sure you understood what I was trying to say, but you summarized it well, in that we can’t understand God’s “world”. He tells us that, and I believe it.
We can, however, trust what He tells us in his Word, and that is that he is outside time, and it does not define or constrain his actions. He created it, and can deal with it as it suits Him.
