Biblical spirituality

In his book on the pursuit of scholarly virtue, Excellence Andreas J. Kostenberger defines Biblical spirituality in what I view as a very helpful definition:

"Spirituality involves the presence, activity, and work of the Holy Spirit in a believer's life, beginning at conversion and regeneration, and continuing on throughout the entire process of sanctification." (71)

Kosetnberger goes on to write, "The New Testament connects spirituality closely with active obedience and with an engagement of the world as we embark on our mission for God. Spirituality is rarely, if ever, tied to a withdrawal or seclusion from the world as exemplified by the monastic tradition throughout the centuries." (71)
