Christian proclamation might make the gospel audible, but Christians living together in local congregations make the gospel visible (see John 13:34-35). The church is the gospel made visible.
Mark DeverIf you think that the gospel is all about what we can do, that the practice of it is optional, and that conversion is simply something that anyone can choose at any time, then I'm concerned that you'll think of evangelism as nothing more than a sales job where the prospect is to be won over to sign on the dotted line by praying a prayer, followed by an assurance that he is the proud owner of salvation.
