Where did God come from? God came from That "Stuff"-In-The-Infinite-Span-Of-Time before eternity began.
In seminary more than 50 years ago, I read that the ancient conceptualization of eternity was not endless time, but time out-of-mind. That is, "eternity" was to the ancients a length of time that is incomprehensible, a period that indeed has an end, but whose end is so incomprehensibly distant that it is unconceivable to our human imaginations. So something "eternal" may still have an end, a finish at the "end of the age" of whatever age it is. Eternity was considered by the ancients to be FINITE, only "never-ending" to our line of thought.
Not so the infinite time before eternity began. While eternity is a packet of time, a distinct moment in the infinite, infinite time stretches out endlessly both before and after eternity's hiccup event. The hiccup is a necessary moment of movement in what That-In-The-Infinite-Span-Of-Time is doing. What That-In-The-Infinite-Span-Of-Time is doing is evolving Itself from Its assumption of being manifest into actualized manifestation. The No-thing is becoming Thing, the Formless . . . Form. Same stuff, just different states. That-In-The-Infinite-Span-Of-Time planned what It would be, then believed that It was. It is now working on Its own manifestation becoming completely realized.
The process of developing the nature and characteristics of That-In-The-Infinite-Span-Of-Time into permanent manifestation takes awhile. There is transition to be made through choice and decision, discipline and practice. Some things may have a long setup, there might be a lot of failures. A lot of patience is required.
I have resolved that THIS world/universe we are in and of is an image of THAT world, for we are from and are becoming that one. That-In-The-Infinite-Span-Of-Time has become us, that we might become It in this manifestation.
This is key: whatever was (and is) in the infinite time before eternity, "That," at some point BECAME conscious. As Its image, we need to do that, too. We need to become conscious. That-In-The-Infinite-Span-Of-Time became conscious of Itself, conscious of what it is, conscious of what had transpired in its becoming conscious, conscious of all that It could be, and conscious of Its own imperfection in not being manifest in this dimension. "Oops, I'm missing something." All that That-In-The-Infinite-Span-Of-Time would be if It were all that It could be was imagined, and then assumed by That-In-The-Infinite-Span-Of-Time to exist as the Milta (Miltha). To God (That-In-The-Infinite-Span-Of-Time's consciousness), the Milta absolutely exists--has ALWAYS existed, for the Milta is That-In-The-Infinite-Span-Of-Time manifest. It is believing that It has already received. YOU CAN BET THAT WHAT HE HAS PLANTED, HE IS GOING TO HARVEST.
And this was BEFORE the beginning of eternity. The Milta is the Son of God Who CREATES all things coming into existence in eternity (Genesis 1:1 Alexander). The Milta is every thing's beginning and its end--all things are for Him, through Him, and are to Him. The Milta, the Unmanifest-No-thing-In-The-Infinite-Span-Of-Time Manifest, is the Purpose of Creation. The Milta is with God, and He IS God, and as of right now in this hiccup of eternity, the Milta is incomplete. This is guaranteed to be temporary. I sincerely suggest not trying Its patience, which, like eternity, is finite.
