Thabiti Anyabwile, from his post, The Redundancy of "Radical Discipleship":
I think my walk with Christ took a step in a more radical direction when I began to live actively in a church community. When the local church really became a family I was committed to, nominalism simply ceased to be a viable option. You can't walk together with other saints, commit yourself to the cross-carrying "one anothers" of Scripture, and remain a lukewarm disciple.
