Hello:
Just saw in Faithlife today video Dr. Perrin talking about Jesus related to the temple. I have not started the BI301 yet, but maybe the following can be of help:

My understanding is that we are living stones part of the body of Christ (New Temple), where the Holy Spirit will dwell as new location.
Now just because we are part of the New Temple, that to me does not mean we will eventually have self-existence like God.
Any theological construct (deification, theosis, etc. ) that affirms that eventually we will have self-existence, seems wrong to me.
The only self-existent Being in the Universe is God, we are dependent (as created beings) on Him for existence even if granted eternal life through Christ.
Peace and grace.
