William Burkitt on John 10:11

In these verses our Saviour evidently proves himself to be the true Shepherd of his church, by the marks and signs, by the properties and characters, of a good shepherd; which were eminently found with him; namely, to know all his flock, to take care of them, and to lay down his life for them.

1. Jesus Christ, the great shepherd of his church, hath an exact and distinct knowledge of all his flock: I know my sheep, with a three-fold knowledge, with a knowledge of intelligence and observation: he knows them so as to observe and take notice of them, with a knowledge of care and protection; he knows them so as to defend and keep them. Thus Christ knows his sheep, and is also known of them; that is, he is believed on, beloved, and obeyed by them.

2. He lays down his life for his flock. And for this doth he eminently deserve the title of the good shepherd. (As for his power, he is stiled the great shepherd.) A good shepherd indeed, who not only gives life to his sheep, but gives his own life by way of ransom for his sheep! This example of Christ, the great and good shepherd, in laying down his life for his sheep, teacheth all subordinate and inferior shepherds, to prefer the good of their flock, even before their own lives.
