## you Gentiles are no longer strangers or foreigners, but instead you are fellow-citizens with those set apart for God, those who are members of God's family ##

This is describing the spiritual condition of Gentiles before and after they became believers in the same way as a non-citizen becomes a citizen of a nation. (See: [[rc://en/ta/man/translate/figs-metaphor]])

## no longer strangers ##

"no longer outsiders".

## and foreigners ##

"and non-citizens"

## These are built upon the foundation... ##

Paul compare God's family to a building. Christ being the cornerstone, the apostles being the foundation, and the believers being the structure. (See: [[rc://en/ta/man/translate/figs-metaphor]])

## the whole building of his family fits together and increases as a temple set apart for the Lord ##

Paul continues with the comparison of Christ's family to a building in the way a builder fits stones in the making a building so Christ is fitting us together.

## in whom you also are being built together into a dwelling place for God in the Spirit ##

This describes how believers are being put together to become a place where God will permanently dwell in the Spirit just as a house is a dwelling place for people on earth.
