So He told them this parable, saying, What man among you, if he has a hundred sheep and has lost one of them, does not leave the ninety-nine in the open pasture and go after the one which is lost until he finds it? "When he has found it, he lays it on his shoulders, rejoicing. "And when he comes home, he calls together his friends and his neighbors, saying to them, 'Rejoice with me, for I have found my sheep which was lost!' Luke 15: 3-6
So seek and love the lost sheep!
