He was with God in the beginning. John 1:2
This verse reveals two parts of the great wonder and mystery of what theologians call the Trinity: Father, Son, and Holy Spirit. It’s a wonder and mystery because mere words cannot explain how the Trinity co-exists though analogies exist: water|steam|ice – three states of the same substance, or I can be a father|son|uncle – three roles in one person. Again, the analogies fall short but throughout Scripture there are clearly three distinct personages but one God (the Son praying to the Father to send the Spirit later in the Book of John comes to mind.
Incidentally, I am trying to be extremely careful in my terminology here since many false doctrines stem from the personhood of Jesus Christ and His relationship to the two remaining personages of the Godhead.
So, before there was time or anything else for that matter, the Word – described in John 1:14 as the Son, was with the Father. We don’t know how or if they communicated. We don’t know how long that lasted or if it was even measurable. We just know that they existed…in the beginning.
And that’s all we need to know.
