Not everybody is down with the “young, restless, and reformed.”
A couple of days ago, Scot McKnight shared why he “kissed Calvinism goodbye” (to use the Joshua Harris phrase). Interestingly enough, what it came down to was the warning passages in the OT covanent coupled with the warning passages in Hebrews that did it for him (from reading I. Howard Marshall’s Kept by the Power of God). McKnight’s conclusion was, “I couldn’t contest his [Marshall's] many, many passages that all added up to one thing: genuine believers can lose their faith by throwing it away consciously.”
A couple of things worth noting:
1. I have heard many reasons from various people why they reject Calvinism, but McKnight’s rationale is intriguing (and in my view lacking warrant for wholesale dismissal of Calvinism).
2. Several Reformed theologians have addressed the warning passages in Hebrews, not the least of which are Dr. Tom Schreiner and Wayne Grudem (which he did in a conference here at SBTS).
