151 Then all the tax collectors and the sinners drew near to Him to hear Him. 2 And the Pharisees and scribes complained, saying, "This Man receives sinners and eats with them." 3 So He spoke this parable to them, saying: 4 "What man of you, having a hundred sheep, if he loses one of them, does not leave the ninety-nine in the wilderness, and go after the one which is lost until he finds it? 5 And when he has found it, he lays it on his shoulders, rejoicing. 6 And when he comes home, he calls together his friends and neighbors, saying to them, 'Rejoice with me, for I have found my sheep which was lost!' 7 I say to you that likewise there will be more joy in heaven over one sinner who repents than over ninety-nine just persons who need no repentance.

The parable of the lost sheep is very applicable to the great work of man's redemption. The lost sheep represents the sinner as departed from God, and exposed to certain ruin if not brought back to him, yet not desirous to return. Christ is earnest in bringing sinners home. In the parable of the lost piece of silver, that which is lost, is one piece, of small value compared with the rest. Yet the woman seeks diligently till she finds it. This represents the various means and methods God makes use of to bring lost souls home to himself, and the Saviour's joy on their return to him. How careful then should we be that our repentance is unto salvation!
