1 The parable of the lost sheep, 8 of the piece of silver15
15:1 All the publicans - That is, all who were in that place.It seems our Lord was in some town of Galilee of the Gentiles, from whence he afterward went to Jerusalem, Luk 17:11.
15:3 He spake - Three parables of the same import: for the sheep, the piece of silver, and the lost son, all declare (in direct contrariety to the Pharisees and scribes) in what manner God receiveth sinners.
15:4 Leave the ninety and nine in the wilderness - Where they used to feed: all uncultivated ground, like our commons, was by the Jews termed wilderness or desert. And go after - In recovering a lost soul, God as it were labours. May we not learn hence, that to let them alone who are in sin, is both unchristian and inhuman! Mat 18:12.
15:7 Joy shall be - Solemn and festal joy, in heaven - First, in our blessed Lord himself, and then among the angels and spirits of just men, perhaps informed thereof by God himself, or by the angels who ministered to them. Over one sinner - One gross, open, notorious sinner, that repenteth - That is, thoroughly changed in heart and life; more than over ninety and nine just persons - Comparatively just, outwardly blameless: that need not such arepentance - For they need not, cannot repent of the sins which they never committed. The sum is, as a father peculiarly rejoices when an extravagantchild, supposed to be utterly lost, comes to a thorough sense of his duty; or as any other person who has recovered what he had given up for gone, has a more sensible satisfaction in it, than in several other things equally valuable, but not in such danger: so do the angels in heaven peculiarly rejoice in the conversion of the most abandoned sinners. Yea, and God himself so readily forgives and receives them, that he may be represented as having part in the joy.

14:7 None of us - Christians, in the things we do. Liveth to himself - Is at his own disposal; doeth his own will.
14:10 Or why dost thou despise thy brother - Hitherto the apostle as addressed the weak brother: now he speaks to the stronger.
14:11 As I live - An oath proper to him, because he only possesseth life infinite and independent. It is Christ who is here termed both Lord and God; as it is he to whom we live, and to whom we die. Every tongue shall confess to God - Shall own him as their rightful Lord; which shall then only be accomplished in its full extent. The Lord grant we may find mercy in that day; and may it also be imparted to those who have differed from us! yea, to those who have censured and condemned us for things which we have done from a desire to please him, or refused to do from a fear of offending him. Isa 45:23
