Do not quench the Spirit1 Thessalonians 5:19 RSV
The word for “quench” was used of putting out a fire, and the thought is that the child of God should not put out the sacred fire within.
This verse is parallel with the following:

There is a sin unto death (1 John 5:16).
It is impossible to renew them (Hebrews 6:4-6).
She that giveth herself to pleasure is dead while she lives (1 Timothy 5:6).
Whosoever shall blaspheme against the Holy Spirit hath never forgiveness, but is guilty of an eternal sin (Mark 3:29).
In all seven of the references cited, the unpardonable sin is in view.

The emphasis is ethical, a warning against conduct which might stifle the Spirit’s operation.
Any sin that quenches the Spirit of God in Christian hearts is the eternal and unpardonable sin.
The soul draws back from the contemplation of so terrible a disaster as that.
Oh child of God, keep the holy fire alive.
As the vestal virgins in the ancient Roman temple guarded the sacred flame with their lives and constant devotion, let Christians tend the sacred token of heaven that burns in their souls.
How much more should people who have tasted the good word of God and the powers of the age to come and have been made partakers of the Holy Spirit guard against those evils which continually threaten to quench his blessed presence in their hearts!
