1 Thessalonians 5:19

“Quench not the spirit.] By which is meant, not the person of the Spirit, but either the graces of the spirit, which may be compared to light, and fire, and heat, to which the allusion is in the text; such as faith, which is a light in the soul, a seeing of the Son, and an evidence of things not seen; and love, which gives a vehement flame, which many waters cannot quench; and zeal, which is the boiling up of love, the fervency of it; and spiritual knowledge, which is also light, and of an increasing nature, and are all graces of the spirit: and though these cannot be totally extinguished, and utterly put out and lost, yet they may be greatly damped; the light of faith may become dim; and the…”

“Quench not--the Spirit being a holy fire: "where the Spirit is, He burns" [BENGEL] (Mat 3:11; Act 2:3; Act 7:51). Do not throw cold water on those who, under extraordinary inspiration of the Spirit, stand up to speak with tongues, or reveal mysteries, or pray in the congregation. The enthusiastic exhibitions of some (perhaps as to the nearness of Christ's coming, exaggerating Paul's statement, Th2 2:2, By spirit), led others (probably the presiding ministers, who had not always been treated with due respect by enthusiastic novices, Th1 5:12), from dread of enthusiasm, to discourage the free utterances of those really inspired, in the Church assembly. On the other hand, the caution (Th1 5:21)…”

“Quench not the Spirit - This language is taken from the way of putting out a fire, and the sense is, we are not to extinguish the influences of the Holy Spirit in our hearts.

The Holy Spirit is the source of true devotion, and hence the enkindlings of piety in the heart, by the Spirit, are never to be quenched. Fire may be put out by pouring on water; or by covering it with any incombustible substance; or by neglecting to supply fuel. If it is to be made to burn, it must…”

“Quench not the Spirit - Wherever it is, it burns; it flames in holy love, in joy, prayer, thanksgiving. O quench it not, damp it not in yourself or others, either by neglecting to do good, or by doing evil! 1 Thessalonians 5:20”

“5:19 Do not stifle the Holy Spirit: Paul exhorts the Thessalonian believers not to put out the Spirit’s fire (Matt 3:11; Acts 2:3; 2 Tim 1:6) by prohibiting prophecy in the church (Jer 20:9; 1 Jn 4:1-2).”

“Quench: Sol 8:7; Eph 4:30, Eph 6:16 the Spirit: Gen 6:3; Sa1 16:4; Neh 9:30; Psa 51:11; Isa 63:10; Act 7:51; Co1 14:30; Eph 4:30; Ti1 4:14; Ti2 1:6 1 Thessalonians 5:20”
