Nice article from the work of Paul and Sue Hazelden. Rather than regurgitating it here, I am hoping you will take the time to click and read their article HERE.

Of course, it must be noted that the Engel Scale is cognitive… so it does not really include the affective aspect. If you want to look at The Gray Matrix Extended, that combines the Modified Engel Scal with the affective axis, Click on this article HERE.

As both would note, these don’t define a methodology. Rather they provides a perspective to understand spiritual transformation. So the role of social ministry, dialogue, and such are not dealt with in detail.

Additionally, as I have also noted before, In This Other Article, one could add an additional axis, to include the role of behavior. While as Evangelicals, we like to emphasize that salvation is by faith, not by works, it is also true that in many cultures people often start by adjusting their behavior to a faith community, before actually responding in faith. Even in more individualistic cultures, often connecting behaviorally with a loving community of believers (whether church, ngo, bible study, or otherwise), brings one close to a position to respond to the message of Christ. Of course, the opposite is true also, interacting with hypocritical or mean-spirited or cold Christians can lead to negative perceptions affectively, and then to cognitive and behavioral.
