1 Thessalonians, Chapter 4, verses 1-12
1 He exhorteth them to go on forward in all manner of godliness, 6 to live holily and justly, 9 to love one another, 11 and quietly to follow their own businessLuke, Chapter 15, verses 1-10
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.

4:1 More and more - It is not enough to have faith, even so as to please God, unless we abound more and more therein.
4:3 Sanctification - Entire holiness of heart and life: particular branches of it are subjoined. That ye abstain from fornication - A beautiful transition from sanctification to a single branch of the contrary; and this shows that nothing is so seemingly distant, or below our thoughts, but we have need to guard against it.
4:4 That every one know - For this requires knowledge, as well as chastity. To possess his vessel - His wife. In sanctification and honour - So as neither to dishonour God or himself, nor to obstruct, but further, holiness; remembering, marriage is not designed to inflame, but to conquer, natural desires.
4:5 Not in passionate desire - Which had no place in man when in a state of innocence. Who know not God - And so may naturally seek happiness in a creature. What seemingly accidental words slide in; and yet how fine, and how vastly important!
4:6 In this matter - By violating his bed. The things forbidden, here are three: fornication, Th1 4:3;the passion of desire, or inordinate affection in the married state, Th1 4:5; and the breach of the marriage contract.
4:8 He that despiseth - The commandments we gave.Despiseth God - Himself. Who hath also given you his Holy Spirit - To convince you of the truth, and enable you to be holy.What naked majesty of words! How oratorical, and yet with what great simplicity! - a simplicity that does not impair, but improve, the understanding to the utmost; that, like the rays of heat through a glass, collects all the powers of reason into one orderly point, from being scattered abroad in utter confusion.
4:9 We need not write - Largely. For ye are taught of God - By his Spirit.
4:11 That ye study - Literally, that ye be ambitious: an ambition worthy a Christian. To work with your hands - Not a needless caution; for temporal concerns are often a cross to them who are newly filled with the love of God.
4:12 Decently - That they may have no pretence to say, (but they will say it still,) "This religion makes men idle,and brings them to beggary." And may want nothing - Needful for life and godliness. What Christian desires more?
