I will share one more point which I think everyone can agree on, even though there be differences of understanding in our earthly experience.
Solomon spoke of, not only the heaven we see above, but also the heaven of heavens, not being able to contain God, which the ancients understood to mean that all creation is in God, like a womb inside a mother:
But will God in very deed dwell on the earth? behold, heaven and the heaven of heavens can't contain you; how much less this house that I have built!
Now from man's experience, they could argue with Solomon saying, "Of course he dwells on the earth...he is dwelling in the most holy place is he not?" And they would be correct, but that does not mean Solomon was not correct. They both would be, it is all a matter of perspective. One doesn't discount the other.
Speaking of the Word, before becoming flesh, John wrote that everything that is created was created in the Word:
Everything existed by his hand and without him not even one [thing] existed. That which existed in him was life and the life was the light of men.
(Joh 1:3-4 MGI)
And then, to me, the most powerful expression of this truth is Paul's witness, that everything that was built, including thrones, lordships, rulers, and authorities, which we in the East understand to mean evil powers of darkness, was built in him, and that they stand in him. Apart from him nothing can exist, or stand:
And in him everything that is in heaven and on earth was built, all that is seen and all that is not seen, whether thrones or lordships or rulers or authorities, everything [is] by way of him and was built in him. And he is in front of all and everything stands in him.
(Col 1:16-17 MGI)
Those espousing dualistic Greek thinking will probably not like this, but it is what the earliest believers understood, and is why I share it as an alternative starting point, the one Athanasius held to, instead of the more common understanding today built out of a framework starting from separation, as Augustine held to.
This that I have shared is not in opposition to one's responsibility to confess Yeshua, to turn to God, to live as one connected to the Head, who is Messiah, nor of the need to be saved.
If people are in a room full of light and their eyes are closed, they will be fumbling as those who are lost in the dark. This does not negate both truths, that they are in the room, and in the light (God's reality), yet at the same time, they are walking in darkness (man's reality). They do not need to have someone lead them to the room to enter it (they are already inside it). What they need is for someone like Paul to 'open their eyes, so that they will turn from darkness to the light and from the authority of Satan to God and they will receive forgiveness of sins and a portion with the holy [ones] by faith that [is] in me.' (Act 26:18 MGI)
They are like the Greeks he spoke to, who were blindly groping about trying to find the God they were inside the whole time! This is why there is so much emphasis on opening the eyes, having the eyes of the heart enlightened, etc, not for the purpose of entering into Messiah, but to realize where they are and grow in their experience of that truth.
