I am a born-again Jew....Yes, they are. How in the world are you concluding otherwise? The church is the body of Christ. Any saved person is in the body of Christ/church. This is Christianity 101. How can you not be aware of things like this?
What believers are not in the church? Any true believer belongs to Christ and is therefore part of the body of Christ/church.
Yes, of course they are! How can you say otherwise? There is no other name by which anyone has been saved (Acts 4:12), so all believers throughout history are part of the bride and body of Christ.
What are you talking about?
You're not doing that at all, so I guess you start now.
And, you are a spiritual Israelite.
Interesting.
