Ezk 34:11-12,16

It was prophesied in the Old Testament that God would seek the lost sheep. (Ezk 34:11-12,16)

Ezk 34:11 For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out. 12 As a shepherd seeketh out his flock in the day that he is among his sheep that are scattered; so will I seek out my sheep, and will deliver them out of all places where they have been scattered in the cloudy and dark day. 16 will seek that which was lost, and bring again that which was driven away, and will bind up that which was broken, and will strengthen that which was sick: but I will destroy the fat and the strong; I will feed them with judgment.

As prophesied in the Old Testament, Jesus came to this earth to seek lost lambs. (Lk 15:3-7)

Lk 15:3 And he spake this parable unto them, saying, 4 What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it? 5 And when he hath found it, he layeth it on his shoulders, rejoicing. 6 And when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost. 7 I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
