We cannot Join The Church

Being Joined To "His Body"

There is only one church today, and that is “the church, which is His body” (Eph. 1:22b-23a) of which the risen Christ is “the Head.” This is the only church that the Scriptures recognize during today’s age of “the dispensation of the grace of God.”

But the question then is; Who are the members of this church?

Then also; How does one join this church today?
