Isa 43:10 Ye [are] my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I [am] he: before me there was no God formed, neither shall there be after me.
If there is some basic essence that is eternal (before truth and light in my earlier reply), then indeed there were none formed before or after, at least in whatever that essence is. At least that is my first reaction to that in light of the other.
I'll return later to consider this again. But for now it is bedtime. Nighters.
Moses 1
3 And God spake unto Moses, saying: Behold, I am the Lord God Almighty, and Endless is my name; for I am without beginning of days or end of years; and is not this endless?
4 And, behold, thou art my son; wherefore look, and I will show thee the workmanship of mine hands; but not all, for my works are without end, and also my words, for they never cease.
5 Wherefore, no man can behold all my works, except he behold all my glory; and no man can behold all my glory, and afterwards remain in the flesh on the earth.
I don't think it could be any clearer!
6 And I have a work for thee, Moses, my son; and thou art in the similitude of mine Only Begotten; and mine Only Begotten is and shall be the Savior, for he is full of grace and truth; but there is no God beside me, and all things are present with me, for I know them all.
