3 Bible Verses about Lost Sheep

For you were like lost sheep, but are now returned to the shepherd and bishop of your souls.

I tell you most truly, he that enters not by the door into the sheepfold, but climbs in at some other place, he is a thief and robber; but he that enters by the door is the shepherd of the sheep. To him the gate-keeper opens, and the sheep hear his voice, and he calls his sheep by name, and leads them out.read more.
When he puts out all his sheep he goes before them, and the sheep follow him; for they know his voice. But a stranger they will not follow, but will flee from him, for they know not the voice of strangers. This parable spoke Jesus to them, but they knew not what the words which he spoke to them meant. Then said Jesus to them again, I tell you most truly, I am the door of the sheep. All who came before me are thieves and robbers; but the sheep have not heard them.

Jesus answered them, I have told you and you believe not; the works which I perform in my Father's name, these testify of me; but you believe not, because you are not of my sheep. As I said to you, My sheep hear my voice and I know them, and they follow me,
