‘The error that we must emphatically repudiate is the often held notion that the gospel is the power of God only to get us converted. I once heard a missionary speaker report how a pastor in the mission field wrote to headquarters concerning his flock: “We all know the gospel here, and now we must go on to something more solid.” The idea is that the gospel is the gateway to Christian experience, and thus to eternal life, but once we enter that gateway we move on to another more solid reality by which we progress. Sanctification, or becoming holy, or growing in the Christian faith, is frequently [wrongly] depicted as a new stage after conversion. The means to it is variously presented. For some it is by an act of “total commitment,” or of “self emptying” or of “putting to death the old nature.” For others it is a distinct crisis experience of the Holy Spirit. Christian literature and preaching is full of “steps to the deeper life” or “keys to the abundant and victorious life.” This is not to quibble over pious jargon and terminology. The point at issue is simply this: When we approach sanctification as attainable by any means other than the gospel of Christ–the same gospel by which we are converted–we have departed from the teaching of the New Testament.’
