Grieving & Quenching the Spirit
I think grieving and quenching are related, but different.
On grieving:
“Let no unwholesome word come out of your mouth, but if there is any good word for edification according to the need of the moment, say that, so that it will give grace to those who hear. Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.” (Ephesians 4:29–30, NASB 2020)
On quenching:
“Do not quench the Spirit, do not utterly reject prophecies, but examine everything; hold firmly to that which is good, abstain from every form of evil.” (1 Thessalonians 5:19–22, NASB 2020)
I think all fleshliness grieves and quenches Holy spirit.
To speak of grieving Him is to speak of the effect fleshliness has on the Spirit of God in us. He wants better for us, and it breaks His heart, so to speak, when we live as though we were still in the flesh.
To speak of quenching Him is to speak of the effect fleshliness has on our own spirit. When we fail to listen, hear, and yield to Holy Spirit, our spirit cannot receive and benefit from what He is telling us. His voice in us is muffled as though we were wearing spiritual ear plugs.
Saints, as the writer of Hebrews urges, “let’s consider how to encourage one another to love and good works” (Hebrews 10:24).
Let’s follow the guidance of our Brother Paul who urged, “So, as those who have been chosen of God, holy and beloved, put on a heart of compassion, kindness, humility, gentleness, and patience; bearing with one another, and forgiving each other, whoever has a complaint against anyone; just as the Lord forgave you, so must you do also. In addition to all these things put on love, which is the perfect bond of unity. Let the peace of Christ, to which you were indeed called in one body, rule in your hearts; and be thankful.” (Colossians 3:12–15, NASB 2020)
