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!Likewise I say unto you,.... As before, in Luke 15:7

there is joy in the presence of the angels of God; who are the friends and neighbours of Christ: See Gill on Luke 15:6,

over one sinner that repenteth; which they have knowledge of, either by immediate revelation from God, or by observation in the church where they attend: the reason of this joy is, because there is one rescued out of the hands of Satan and his angels, between whom and them, there is an implacable enmity; and because another subject is added to Christ's kingdom, and by which it is enlarged, the prosperity of which they greatly desire; and because another heir is born in that family, to which they belong, and they have another social worshipper with them: and this joy is said to be "in the presence of" them; and so may design the joy of others, as of Father, Son, and Spirit, which is in their sight and knowledge; and also the joy there is among themselves.
