1-thessalonians 5:19

Quench not the Spirit - The Holy Spirit is represented as a fire, because it is his province to enlighten and quicken the soul; and to purge, purify, and refine it. This Spirit is represented as being quenched when any act is done, word spoken, or temper indulged, contrary to its dictates. It is the Spirit of love, and therefore anger, malice, revenge, or any unkind or unholy temper, will quench it so that it will withdraw its influences; and then the heart is left in a state of hardness and darkness. It has been observed that fire may be quenched as well by heaping earth on it as by throwing water on it; and so the love of the world will as effectually grieve and quench the Spirit as any ordinary act of transgression.

Every genuine Christian is made a partaker of the Spirit of God; and he who has not the spirit of Christ is none of his. It cannot be the miraculous gifts of the Spirit which the apostle means, for these were given to few, and not always; for even apostles could not work miracles when they pleased; but the direction in the text is general, and refers to a gift of which they were generally partakers.

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. Possibly there may be an allusion here to fire on an altar, which was to be kept constantly burning. This fire may have been regarded as emblematic of devotion, and as denoting that that devotion was never to become extinct. 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 be nourished with proper care and attention. The Holy Spirit, in his influences on the soul, is here compared with fire that might be made to burn more intensely, or that might be extinguished.

In a similar manner the apostle gives this direction to Timothy, "I put thee in remembrance that thou stir up ἀναζωπυρεῖν anazōpurein, kindle up, cause to burn) the gift of God;" 2 Timothy 1:6. Anything that will tend to damp the ardor of piety in the soul; to chill our feelings; to render us cold and lifeless in the service of God, may be regarded as "quenching the Spirit." Neglect of cultivating the Christian graces, or of prayer, of the Bible, of the sanctuary, of a careful watchfulness over the heart, will do it. Worldliness, vanity, levity, ambition, pride, the love of dress, or indulgence in an improper train of thought, will do it. It is a great rule in religion that all the piety which there is in the soul is the fair result of culture. A man has no more religion than he intends to have; he has no graces of the Spirit which he does not seek; he has no deadness to the world which is not the object of his sincere desire, and which he does not aim to have. Any one, if he will, may make elevated attainments in the divine life; or he may make his religion merely a religion of form, and know little of its power and its consolations.

5:19 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!
