Ephesians 2:19-22

So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.

-Ephesians 2:19-22

I find this a little confusing, but let's walk through this and see where we get.  As a result of what Paul has talked about so far, he goes on to say that those now brought near are those who are "members of the household of God".  Moreover, they are "fellow citizens with the saints".  One new man has been created and there peace so that even the Gentiles can be brought in together with the saints.  NLT puts it this way, "You are members of God's family".

From here, Paul moves on to talk more about "the household of God".  Though it is at first mentioned like a family, it is now moreso referred to as an actual house or home building.  This home has a foundation, which is "the apostles and prophets".  Because of the apostles and prophets, this house could be built, since a house needs a foundation to be build properly.  The most important part about this house is that Christ Jesus is the cornerstone.  The corner stone extremely important and is what the house depends on.  Christ Jesus, the cornerstone, is "in whom the whole structure, being joined together, grows into a holy temple in the Lord".  Jesus really is important to this house and Paul makes it clear, just in case being referred to as the cornerstone wasn't enough.  It is through Jesus that the structure grows or becomes a holy temple for God.

We are not only members of God's family, but we are now part of his house.  We are his house, or at least that is what we grow into or become part of.  Perhaps I don't fully get it, but we do see that this happens because of Jesus by his Spirit.  If I think about the things that the Spirit does, it makes me think of the Spirit's work after Jesus is gone.  I think of sanctification, which I guess we read from here is part of what causes us to be built together into a dwelling place for God.  It's important to note that this isn't just you alone, but together.  It's interesting to see the pictures or illustrations that God uses to tell us things.  I think that as we dwell upon them and ask God for wisdom and understanding, he may tell us more and more.  It's cool to think that we are becoming something worthy for God to dwell in, in some sense.
