If you are interested in the general topic of Spiritual Formation, you might want to check out 14 entries I have written for the Daily Devotional booklet, Words of Hope (from February 1, 2016 to February 14. You can find them online on the Words of Hope website (If the link is broken, here is the address: woh.org/word/devotionals/)
This is the definition I used for the devotionals. The first lines were written by M. Robert Mulholland (in Invitation to a Journey) and that concept was elaborated on by developed by James Bryan Smith:
“Christian spiritual formation is the process of being conformed into the image of Christ, through a relationship of intimacy with God, by the power of the Spirit, in order to live a good and beautiful life of faith, hope, love, joy, and peace—a life that will be a blessing to oneself and to others and will glorify God now and for all eternity” (by James Bryan Smith in “Defining Spiritual Formation: The How”, the third post on this topic on the Apprentice Institute blog)
As usual, these are my very personal reflections about how a belief system needs to be supported by a personal, intimate relationship with God and training to become more like Jesus. Perhaps they will be helpful to you.
