From this you assume pre-existence.
You may need to further consider John's teachings in John 3:13
"even the Son of man which is in heaven". Did the Son of man literally come down from heaven?
If you so believe, then Flesh can glory in His Presence!
This begs the question Brakelight...in what way can it be said the Master came from Heaven? What about John 6:33, 38 & 51?
The other nuance to Johns teaching which you need to explore is the Old Testament language of theophany (God appearing). A manifestation of divine power is referred to as "God coming down". The completion of the theophany is God "going up" or ascending. (Genesis 11:5; 18:21; Exod. 3:7, 8; 19:11, 18, 20; 34:5; Psa. 18:9, 10; Isa. 64:1.)
And yet the word “theophany” does not appear in any biblical manuscripts.
If God appeared to man, it would be a fatal exercise.....(Exodus 33:17-20)
The apostle John said.....
”No man has seen God at any time; the only-begotten god who is at the Father’s side is the one who has explained Him.” (John 1:18)
How many people saw Jesus?
The one who was “with God”, “at the Father’s side”, for eons before creation, explained to others who he was, and always will be.....the “one God” of Israel. (Deut 6:4; John 17:3)
God never “came down” as he is the Almighty and does not need to reduce himself in any way to accomplish his will and purpose. He does that by empowering his servants to do what is necessary to make adjustments in his responses to their decisions.
The flood of Noah’s day is a prime example of that. God did not save Noah out of that world....he instructed Noah about how to save himself and his family. It would require monumental effort.
If God’s instructions are followed, good is accomplished, but if it is ignored or rejected, trouble is not far away.
God’s purpose will stand, no matter what choices his free willed children might make to counter it. Jesus is called “God’s holy servant”....something not mentioned in Christendom as it would expose a great deal of false teaching. (Acts 4:27, 30) Can God be his own “servant”?
Can God be his own “apostle and High Priest”? (Heb 3:1)
Also, Jesus did not literally come down from Heaven.
He said he did...John 6:38....whom should we believe?
He was God’s “master workman” in creation. (Prov 8:30-31)
His origin was heavenly, (as the context states - John 3:31), in-so-far as he was conceived by the Holy Spirit sent from heaven and his teaching was not his own but his Father's. (Luke 1:35; John 7:16; 17:14).
His life was in existence in the spirit realm before he became a human through the power of God’s spirit.
He is the very beginning of God’s creation (Rev 3:14)....he is the “us” and “our” in Gen 1:26. God’s “firstborn”. (Col 1:15-17) He was a glorious spirit creature before he became Jesus the human, (John 17:5, 24) willing to sacrifice his life on behalf of those whose lives were turned upside down by the actions of one man. Adam could have altered the course of history if he had only remained obedient. The death of the entire human race was laid squarely at his feet. (Rom 5:12)
If, you study this for yourself, which I know you will do, the truth will become clear.
We can say the same to you.....you too could be misled by the great deceiver......Jesus will make it known soon enough who is a “sheep” and who is a stubborn “goat”. (Matt 7:21-23)
