As I'm about to go into seminary, I found this quote intriguing:
Discipleship is not limited to what you can understand – it must transcend all comprehension. Plunge into the deep waters beyond your own understanding, and I will help you to comprehend.
Bewilderment is the true comprehension. Not to know where you are going is the true knowledge. In this way Abraham went forth from his father, not knowing where he was going. That is the way of the cross. You cannot find it in yourself, so you must let me lead you as though you were a blind man.
Not the work which you choose, not the suffering you devise, but the road which is contrary to all that you choose or contrive or desire – that is the road you must take. It is to this path that I call you, and in this sense that you must be my disciple.
Martin Luther (1483-1546), quoted in Dietrich Bonhoeffer, "The Cost of Discipleship."
