I finished Frederica Mathewes-Green's The Illumined Heart while camping and have to say for such a small book it packs a mighty big punch. While it is coming from her Orthodox milieu, the practices she unpacks would apply to any Christian serious about strengthening their relationship with Christ. She compares early Christians and their outlook and reaction with, well, us. In a motherly way, Mathewes-Green shows how wussy we are--well, at least me. Prayer, fasting (the Orthodox way), repentance, she covers the basics that are so easily overlooked. Tolle, lege, really!
Khouria, you make me want to head to Constantinople now!
