For our exhortation. He confirms, by another argument, the Thessalonians in the faith which they had embraced -- inasmuch as they had been faithfully and purely instructed in the word of the Lord, for he maintains that his doctrine was free from all deception and uncleanness. And with the view of placing this matter beyond all doubt, he calls their conscience to witness. The three terms which he makes use of may, it would seem, be distinguished in this manner: imposture may refer to the substance of doctrine, uncleanness to the affections of the heart, guile to the manner of acting. In the first place, therefore, he says that they had not been deluded or imposed upon by fallacies, when they embraced the kind of doctrine that had been delivered to them by him. Secondly, he declares his integrity, inasmuch as he had not come to them under the influence of any impure desire, but actuated solely by upright disposition. Thirdly, he says that he had done nothing fraudulently or maliciously, but had, on the contrary, manifested a simplicity befitting a minister of Christ. As these things were well known to the Thessalonians, they had a sufficiently firm foundation for their faith.

For our exhortation - That is, the exhortation to embrace the gospel. The word seems to be used here so as to include preaching in general. The sense is, that the means which they used to induce them to become Christians were not such as to delude them.
Was not of deceit - Was not founded on sophistry. The apostle means to say, that the Thessalonians knew that his manner of preaching was not such as was adopted by the advocates of error.
Nor of uncleanness - Not such as to lead to an impure life. It was such as to lead to holiness and purity. The apostle appeals to what they knew to be the tendency of his doctrine as an evidence that it was true. Most of the teaching of the pagan philosophers led to a life of licentiousness and corruption. The tendency of the gospel was just the reverse.Nor in guile - Not by the arts of deceit. There was no craftiness or trick, such as could not bear a severe scrutiny. No point was carried by art, cunning, or stratagem. Everything was done on the most honorable and fair principles. It is much when a man can say that he has never endeavored to accomplish anything by mere trick, craft, or cunning. Sagacity and shrewdness are always allowable in ministers as well as others; trick and cunning never. Yet stratagem often takes the place of sagacity, and trick is often miscalled shrewdness. Guile, craft, cunning. imply deception, and can never be reconciled with that entire honesty which a minister of the gospel, and all other Christians, ought to possess; see notes on 2-Corinthians 12:16; compare Psalm 32:2; Psalm 34:13; John 1:47; 1-Peter 2:1, 1-Peter 2:22; Revelation 14:5.

Our exhortation - The word παρακλησιςhas a very extensive meaning; it signifies not only exhortation and teaching in general, but also encouragement, consolation, and the like. When the apostles exhorted or admonished men, it was that they should turn from evil to good, from misery to happiness, from Satan to God, and from hell to heaven. Their exhortations having this object, every word was consolatory; and as the truth which they delivered was unquestionable, therefore their ministry was a subject of the highest encouragement and joy.
Not of deceit - We did not endeavor to allure you with false pretences; we did not deceive you, nor were we deceived ourselves.
Nor of uncleanness - Such as the teachings of the Gentile philosophers were; their supreme gods were celebrated for their adulteries, fornications, uncleannesses, thefts, barbarities, and profligacies of the most odious kind. Our Gospel was pure; came from the pure and holy God; was accompanied with the influences of the Holy Spirit, and produced purity both in the hearts and lives of all that received it.
Nor in guile - We had no false pretences, and were influenced by no sinister motives.

(3) For our exhortation [was] not of deceit, nor of (b) uncleanness, nor in guile:
(3) To teach pure doctrine faithfully and with a pure heart.
(b) By any wicked and evil type of dealing.

For our exhortation,.... Or "consolation"; for the ministry of the Gospel, which is here meant, consists of doctrines full of comfort to distressed minds, such as free justification by the righteousness of Christ, full pardon by his blood, and complete satisfaction by his sacrifice; as well as of exhortations to the exercise of grace and discharge of duty: and this was
not of deceit; or "error", was not "fallacious", as the Ethiopic version renders it; it consisted of nothing but truth, it was the word of truth, and the truth as it is in Jesus; nor did it proceed from any intention to deceive and impose on persons; it was no imposture:
nor of uncleanness; it did not spring from any impure affection for any sin, for popular applause, or worldly interest; nor did the ministers of it connive at uncleanness in others, or practise it themselves, as did the false teachers; but bore their testimony against it, both by word and example, and taught no doctrine that encouraged to it; but, on the contrary, the doctrine which is according to godliness, and which teaches men to deny ungodliness and worldly lusts:
nor in guile; as there was no deceitful design in the ministry of the word, nor anything impure and immoral in the matter of it; so there was no artifice used in the dispensing of it; it was plain and simple, without any colour and guile, without the hidden things of dishonesty, without craftiness and handling the word deceitfully; and this is a reason why the apostles preached it with so much freedom and boldness, because there was nothing false, impure, or artful in it.

For--The ground of his "boldness" (1-Thessalonians 2:2), his freedom from all "deceit, uncleanness, and guile"; guile, before God, deceit (Greek, "imposture"), towards men (compare 2-Corinthians 1:12; 2-Corinthians 2:17; Ephesians 4:14); uncleanness, in relation to one's self (impure motives of carnal self-gratification in gain, 1-Thessalonians 2:5), or lust; such as actuated false teachers of the Gentiles (Philippians 1:16; 2-Peter 2:10, 2-Peter 2:14; Jde 1:8; Revelation 2:14-15). So Simon Magus and Cerinthus taught [ESTIUS].
exhortation--The Greek means "consolation" as well as "exhortation." The same Gospel which exhorts comforts. Its first lesson to each is that of peace in believing amidst outward and inward sorrows. It comforts them that mourn (compare 1-Thessalonians 2:11; Isaiah 61:2-3; 2-Corinthians 1:3-4).
of--springing from--having its source in--deceit, &c.

For our exhortation - That is, our preaching. A part is put for the whole. Is not, at any time, of deceit - We preach not a lie, but the truth of God. Nor of uncleanness - With any unholy or selfish view. This expression is not always appropriated to lust, although it is sometimes emphatically applied thereto. Nor in guile - But with great plainness of speech.
