It is also said that the sheep heed the Shepherd, because they know his voice. Is it true that men recognize Christ's call and respond to it? In one sense it must be, for he has said so; yet much in me qualifies the statement. Actually I respond much more readily to the call of 'the others'; I neither really understand Christ's summons nor follow it. Therefore, in order that I may hear, he must not only speak, but also open my ears to his voice. Part of me, the profoundest part, listens to it, but superficial, loud contradiction often overpowers it. The opponents with whom God must struggle in order to win us are not primarily ‘the others,’ but ourselves; we bar his way. The wolf who puts the hireling to flight is not only outside; he is also within. We are the arch-enemy of our own salvation, and the Shepherd must fight first of all with us – for us.

The constant talker will never, or a least rarely, grasp truth. Of course even he must experience some truths, otherwise he could not exist. He does notice certain facts, observe certain relations, draw conclusions and make plans. But he does not yet possess genuine truth, which comes into being only when the essence of an object, the significance of a relaton, and what is valid and eternal in this world reveal themselves. This requires the spacousness, freedom, and pure receptiveness of that inner “clean-swept room” whilch silence alone can create

To understand antiquity’s idea of man, we must examine its gods and heroes, myths and legends. In these we find the classical prototype of genuine man. ... the will to greatness, wealth, power and fame. Anything opposed to it falls short of the authentically human. ...What a world of difference between this conception and that to which Christ has led us! ...Jesus’ friends are in no way remarkable for their talent or character. He who considers the apostles or disciples great from a human or religious point of view raises the suspicion that he is unacquainted with true greatness. Moreover, he is confusing standards, for the apostle and disciple have nothing to do with such greatness. Their uniqueness consists of their being sent, of their God-given role of pillars for the coming salvation.
