The Journal of Spiritual Formation and Soul Care is put out by Biola/Talbot. It is a peer-reviewed, twice-per-year journal with some theological weight to it. It is a bit pricey for a one year subscription ($30), but I have found it an excellent resource that has sharpened my thinking and teaching biblically and theologically on the subject at hand as well as guide me in my personal journey.
Individual volumes can be purchased. I would highly recommend Spring 2014 (Vol. 7, No. 1) and the special section on The Practice of Contemplative Prayer in an Evangelical Context. This is Biblically wonderful writing. With all the buzz on contemplative spirituality out there, these articles provide biblical grounding and guidance for contemplative practices.
