Well, Creed?
I hope those jackals don't keep you from answering.
Sure thing, Mr. McDonald. I'm sorry, I was waiting for one of your workers to fix the ice cream machine again.
The TIME when God was by Himself (not 'Themselves")?
Again, time is a created entity. So, the start of creation is time as we know it - past present and future.
Psalm 148:2-5 - Praise ye him,
all his angels: praise ye him, all his hosts. Praise ye him, sun and moon: praise him, all ye stars of light. Praise him, ye heavens of heavens, and ye waters that be above the heavens. Let them praise the name of the Lord: for
he commanded, and they were created.
Angels are also created beings but happened in only what us finite creatures can understand as "eternity."
The TIME when He begot/created His son?
The Son was not created and has always existed in the eternal realm. In the realm of time, He was begotten when he was conceived in Mary's womb.
Hebrews 1:5 - For unto which of the angels said he at any time, Thou art my Son,
this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
The TIME when He empowered His son to make all things?
John 1:1 -
In the beginning was the Word, and the Word was with God, and the Word was God.
