16 Have joy at all times. 17 Keep on with your prayers. 18 In everything give praise: for this is the purpose of God in Christ Jesus for you. 19 Do not put out the light of the Spirit; 20 Do not make little of the words of the prophets; 21 Let all things be tested; keep to what is good; 22 Keep from every form of evil.

23 And may the God of peace himself make you holy in every way; and may your spirit and soul and body be free from all sin at the coming of our Lord Jesus Christ. 24 God, by whom you have been marked out in his purpose, is unchanging and will make it complete.

Commentary on 1 Thessalonians 5:16-22

(Read 1 Thessalonians 5:16-22)

We are to rejoice in creature-comforts, as if we rejoiced not, and must not expect to live many years, and rejoice in them all; but if we do rejoice in God, we may do that evermore. A truly religious life is a life of constant joy. And we should rejoice more, if we prayed more. Prayer will help forward all lawful business, and every good work. If we pray without ceasing, we shall not want matter for thanksgiving in every thing. We shall see cause to give thanks for sparing and preventing, for common and uncommon, past and present, temporal and spiritual mercies. Not only for prosperous and pleasing, but also for afflicting providences, for chastisements and corrections; for God designs all for our good, though we at present see not how they tend to it. Quench not the Spirit. Christians are said to be baptized with the Holy Ghost and with fire. He worketh as fire, by enlightening, enlivening, and purifying the souls of men. As fire is put out by taking away fuel, and as it is quenched by pouring water, or putting a great deal of earth upon it; so we must be careful not to quench the Holy Spirit, by indulging carnal lusts and affections, minding only earthly things. Believers often hinder their growth in grace, by not giving themselves up to the spiritual affections raised in their hearts by the Holy Spirit. By prophesyings, here understand the preaching of the word, the interpreting and applying the Scriptures. We must not despise preaching, though it is plain, and we are told no more than what we knew before. We must search the Scriptures. And proving all things must be to hold fast that which is good. We should abstain from sin, and whatever looks like sin, leads to it, and borders upon it. He who is not shy of the appearances of sin, who shuns not the occasions of it, and who avoids not the temptations and approaches to it, will not long keep from doing sin.

Commentary on 1 Thessalonians 5:23-28

(Read 1 Thessalonians 5:23-28)

The apostle prays that they might be sanctified more perfectly, for the best are sanctified but in part while in this world; therefore we should pray for, and press toward, complete holiness. And as we must fall, if God did not carry on his good work in the soul, we should pray to God to perfect his work, till we are presented faultless before the throne of his glory. We should pray for one another; and brethren should thus express brotherly love. This epistle was to be read to all the brethren. Not only are the common people allowed to read the Scriptures, but it is their duty, and what they should be persuaded to do. The word of God should not be kept in an unknown tongue, but transplanted, that as all men are concerned to know the Scriptures, so they all may be able to read them. The Scriptures should be read in all public congregations, for the benefit of the unlearned especially. We need no more to make us happy, than to know the grace of our Lord Jesus Christ. He is an ever-flowing and an over-flowing fountain of grace to supply all our wants.
