Many churches are measuring the wrong things. We measure things like attendance and giving, but we should be looking at more fundamental things like anger, contempt, honesty, and the degree to which people are under the thumb of their lusts. Those things can be counted, but not as easily as offerings.
The core of the person is what he or she loves, and that is bound up with what they worship - that insight recalibrates the radar for cultural analysis. The rituals and practices that form our loves spill out well beyond the sanctuary. Many secular liturgies are trying to get us to love some other kingdom and some other gods.
What you present as the gospel will determine what you present as discipleship. If you present as the gospel what is essentially a theory of the atonement, and you say, 'If you accept this theory of the atonement, your sins are forgiven, and when you die you will be received into heaven,' there is no basis for discipleship.
