4 Bible Verses about Lost Sheep

I go astray, like a sheep that is lost; O seek thy servant, for I do not forget thy commandments.

For ye were as sheep going astray: but are now returned unto the shepherd, and bishop of your souls.

Verily, verily I say unto you, He that entereth not in by the door, into the sheepfold, but climbeth up some other way: the same is a thief and a robber. He that goeth in by the door, is the shepherd of the sheep. To him the porter openeth the door, and the sheep hear his voice; And he calleth his own sheep by name, and leadeth them out.read more.
And when he hath sent forth his own sheep, he goeth before them, and the sheep follow him: For they know his voice. A stranger they will not follow, but will fly from him. For they know not the voice of strangers." This similitude spake Jesus unto them. But they understood not, what things they were, which he spake unto them. Then said Jesus unto them again, "Verily, verily I say unto you: that I am the door of the sheep. All, even as many as came before me, are thieves and robbers: but the sheep did not hear them. I am the door: by me, if any man enter in, he shall be safe, and shall go in and out, and find pasture. The thief cometh not but for to steal and kill, and destroy. I am come that they might have life, and have it more abundantly. I am the good shepherd. The good shepherd giveth his life for the sheep. An hired servant which is not the shepherd, neither the sheep are his own, seeth the wolf coming, and leaveth the sheep, and flyeth: and the wolf catcheth them, and scattereth the sheep. The hired servant flyeth because he is a hired servant, and careth not for the sheep. I am that good shepherd, and know mine, and am known of mine. As my father knoweth me: even so know I my father. And I give my life for the sheep, and other sheep I have, which are not of this fold. Them also must I bring, that they may hear my voice. And that there may be one flock, and one shepherd. Therefore doth my father love me: because I put my life from me, that I might take it again. No man taketh it from me: but I put it away of myself. I have power to put it from me, and power I have to take it again. This commandment have I received of my father." And there was a dissension among the Jews for these sayings, and many of them said, "He hath the devil, and is mad: why hear ye him?" Others said, "These are not the words of him that hath the devil: Can the devil open the eyes of the blind?" And it was at Jerusalem, the feast of the dedication, and it was the winter: And Jesus walked in Solomon's porch. Then came the Jews round about him, and said unto him, "How long dost thou make us doubt? If thou be Christ, tell us plainly." Jesus answered them, "I told you and ye believe not: The works that I do in my father's name, they bear witness of me: but ye believe not, because ye are not of my sheep. As I said unto you, My sheep hear my voice, and I know them, and they follow me.

How think ye? If a man have a hundred sheep, and one of them should be gone astray, doth he not leave ninety and nine in the mountains, and go and seek that one which is gone astray?
