1 Thessalonians, Chapter 4, verses 1-8
1 He exhorteth them to go on forward in all manner of godliness, 6 to live holily and justly25 This chapter contains the last public discourse which our Lord uttered before he was offered up. He had before frequently declared what would be the portion of all the workers of iniquity. But what will become of those who do no harm? Honest, inoffensive, good sort of people? We have here a clear and full answer to this important question.
25:1 Then shall the kingdom of heaven - That is, the candidates for it, be like ten virgins - The bridemaids on the wedding night were wont to go to the house where the bride was, with burning lamps or torches in their hands, to wait for the bride groom's coming.When he drew near, they went to meet him with their lamps, and to conduct him to the bride.
25:3 The foolish took no oil with them - No more than kept them burning just for the present. None to supply their future want, to recruit their lamp's decay. The lamp is faith.A lamp and oil with it, is faith working by love.
25:4 The wise took oil in their vessels - Love in their hearts.And they daily sought a fresh supply of spiritual strength, till their faith was made perfect.
25:5 While the bridegroom delayed - That is, before they were called to attend him, they all slumbered and slept - Were easy and quiet, the wise enjoying a true, the foolish a false peace.
25:6 At midnight - In an hour quite unthought of.
25:7 They trimmed their lamps - They examined themselves and prepared to meet their God.
25:8 Give us of your oil, for our lamps are gone out - Our faith is dead. What a time to discover this! Whether it mean the time of death, or of judgment. Unto which of the saints wilt thou then turn? Who can help thee at such a season?
25:9 But the wise answered, Lest there be not enough for us and you! - Beginning the sentence with a beautiful abruptness; such as showed their surprise at the state of those poor wretches, who had so long received them, as well as their own souls.Lest there be not enough - It is sure there is not; for no man has more than holiness enough for himself. Go ye rather to them that sell - Without money and without price: that is, to God, to Christ.And buy - If ye can. O no! The time is past and returns no more!
25:13 Watch therefore - He that watches has not only a burning lamp, but likewise oil in his vessel. And even when he sleepeth, his heart waketh. He is quiet; but not secure.

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.
