6 And when he cometh home, he calleth together his friends and his neighbors, saying unto them, Rejoice with me, for I have found my sheep which was lost. 7 I say unto you, that even so there shall be joy in heaven over one sinner that repenteth, [more] than over ninety and nine righteous persons, who need no repentance.
Matthew Henry's Commentary on Luke 15:6-7
Commentary on Luke 15:1-10
(Read Luke 15:1-10)
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!
