The gospel is not about us an what we have done; rather it is the Good News for us. The church is not simply the effect of the gospel, but is itself part of the Good News that is promised. That’s why Paul, in his epistles said keeping up divisions between Jews and Gentile is tantamount to denying the gospel. Salvation and the church are not actually different topics.
