It needs the unvarnished truth of the Scriptures. We may merely succeed in adding people to our churches who have never been converted. That will be no help to them and no help to our churches either. To leave someone believing they are converted when they are not is an awful prospect. We must do better.
Failure is too high a price to pay.
