“when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus. They will suffer the punishment of eternal destruction, away from the presence of the Lord and from the glory of his might”
(2 Thessalonians 1:7-9 ESV)

The fire hydrant is the powerful water source that firefighters use to rescue people from the heat of destructive flames. The Word of God is the powerful source of Living Water that the Lord Jesus uses to rescue people from the life destroying fires of sin.
