"I lay in Zion for a foundation a stone, a tried stone, a precious corner stone"
The description of the beginning of the building of the spiritual temple, showing that Christ just as the Apostles were stones of that building's structure.
Ephesians 2:18 "For through him (Jesus) we both have access by one Spirit unto the Father.
19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And
are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone (Revelation 22:9);
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit."
So that is very appropriate what you point out us2are1. We see how it is that Jesus manifest Yahweh to us. His Father's spirit is able to have communion with him because Jesus is holy in his own spirit.
In taking the many on whom his Father called to him to be as brothers (Romans 8:29) Jesus taught them by the bath in the water of the Word to themselves become holy in their spirits that they might also enjoy that same communion as Jesus with his Father's spirit.
Thus they being joined together as one body with Jesus "the building fitly framed together groweth unto an holy temple in the Lord".
Yes, into a holy city among whose holy people God is able to reside.
"builded together (with Jesus as the chief cornerstone) for an habitation of God through the Spirit.
They did not become literally God. But they became one body with Christ and like as Christ they are now able to have direct approach to God by spirit.
The Father is thus now manifested to them just as the Father is, was and has been from Jesus' beginning, manifest to Jesus.
Thus they are even said to set upon Jesus' throne with him, all of them together (including Jesus as the chief among them) sitting next to and at the right hand of the Father in the Father's throne.
Revelation 3:21 "To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne."
How dare anyone resist (or worse, seek to hide) such a beautiful and all important picture of what Our wonderful God is doing in His Son.
Now I want to point out something about Ephesians 2: 21 " In whom all the building fitly framed together groweth unto an holy temple in the Lord:"
The phrase "in the Lord" at the end there, is not what the original language text actually says. I will explain.
The word "the" does not occur there with "lord". "Lord" occurs there with an absence of the definite article. And "lord" minus that definite article actually means "supreme in authority".
So it is actually telling us that this holy temple (Christ and his brethren) exists jointly sharing the supreme authority given it of the Father Yahweh.
