what does the bible say?
“Quenching” and “grieving” the Spirit are similar. In 1 Thessalonians 5:19, Paul uses the same word related to "quenching" or "putting out" a fire (Mark 9:44). In the context of that letter, Paul was encouraging believers to live holy lives according to God's Spirit. They were not to stop doing what they had been instructed to do. They were not to lead a lifestyle that would quench, or put out the fire, of God's Spirit at work among them. Similarly, in Ephesians 4:30, Paul’s instruction not to "grieve the Holy Spirit of God” meant to avoid acting in ways that would be contrary to the desires of or painful to the Spirit. Unlike in Old Testament times, believers today cannot lose the indwelling of the Holy Spirit (Ephesians 1:13), but we can quench or grieve it. Both occur when a believer sins, places self above God and others, or lives like someone without Christ.
