John 10:10-15

The thief comes only in order to steal and kill and destroy. I came that they may have life, and have it in abundance [to the full, till it overflows]. I am the Good Shepherd. The Good Shepherd lays down His [own] life for the sheep. [Ps 23; Is 40:11] But the hired man [who merely serves for wages], who is neither the shepherd nor the owner of the sheep, when he sees the wolf coming, deserts the flock and runs away; and the wolf snatches the sheep and scatters them. The man runs because he is a hired hand [who serves only for wages]and is not concerned about the [safety of the] sheep. I am the Good Shepherd, and I know [without any doubt those who are] My own and My own know Me [and have a deep, personal relationship with Me]— even as the Father knows Me and I know the Father—and I lay down My [very own] life [sacrificing it] for the benefit of the sheep.
