Hell certainly is eternal
Revelation 14:
[9] And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
[10] The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
[11] And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
Those that want to imagine Hell out of existence need to read their Bible wayyy more.

Amen, Brother!
Satan has been casting doubt on the truth of God’s Word since the garden. That’s his oldest tactic.
