There is no mystery in this. What is being said here is do not go to church, be the church. In this manner one may fellowship with all who love Jesus, Yeshua.
I pasted that above from my own previous post. I sometimes get the impression what I have said is not clear, so as an elaboration and clarification, what is meant by "be the church" is the fact that we are all living stones of the Body of Christ. The Head, Jesus, of course, is in heaven having been rejected by the builders. He will return and rebuild His temple.
