3 Bible Verses about Lost Sheep

For, as sheep, ye were going astray; but now ye returned to the Shepherd and Overseer of your souls.

"Verily, verily, I say to you, he that enters not through the door into the fold of the sheep, but climbs up some other way, he is a thief and a robber. But he that enters through the door is shepherd of the sheep. To him the porter opens, and the sheep hear his voice; and he calls his own sheep by name, and leads them out.read more.
When he drives out all his own, he goes on before them, and the sheep follow him; because they know his voice. But a stranger they will in no wise follow, but will flee from him; because they know not the voice of strangers." This parable spake Jesus to them; but they understood not what things they were which He spake to them. Jesus, therefore, said to them again, "Verily, verily, I say to you, I am the door of the sheep. All who came before Me are thieves and robbers; but the sheep did not hear them.

Then occurred the feast of dedication in Jerusalem; and it was winter; and Jesus was walking in the temple in Solomon's porch. The Jews, therefore, came round about Him, and said to Him, "How long dost Thou hold us in suspense? If Thou art the Christ, tell us plainly." Jesus answered them, "I told you, and ye did not believe: the works that I do in My Father's name, these testify concerning Me. But ye believe not, because ye are not of My sheep.
