From time to time, people will say that some doctrines are learned just so you know the right doctrine (“doctrine for doctrine’s sake”). However, it was Augustine who said the goal of theology is not ever merely correct belief. The goal of theology is greater love of God and love of neighbor. This means that in all our pursuit of theological knowledge, two questions to perennially ask ourselves are: how does this amaze me with the reality of God, and how does it help me ‘lock in’ more with a committed life of service to those around me?
To be sure, those will not always be easy answers to uncover (ex: dichtomous view of body and soul), but they are the questions to strain after always, especially if you preach for a living.
