Eternal death

The miserable fate of the wicked in hell (Matt. 25:46; Mark
3:29; Heb. 6:2; 2 Thess. 1:9; Matt. 18:8; 25:41; Jude 1:7). The
Scripture as clearly teaches the unending duration of the penal
sufferings of the lost as the "everlasting life," the "eternal
life" of the righteous. The same Greek words in the New
Testament (aion, aionios, aidios) are used to express (1) the
eternal existence of God (1 Tim. 1:17; Rom. 1:20; 16:26); (2) of
Christ (Rev. 1:18); (3) of the Holy Ghost (Heb. 9:14); and (4)
the eternal duration of the sufferings of the lost (Matt. 25:46;
Jude 1:6).

Their condition after casting off the mortal body is spoken of
in these expressive words: "Fire that shall not be quenched"
(Mark 9:45, 46), "fire unquenchable" (Luke 3:17), "the worm that
never dies," the "bottomless pit" (Rev. 9:1), "the smoke of
their torment ascending up for ever and ever" (Rev. 14:10, 11).

The idea that the "second death" (Rev. 20:14) is in the case
of the wicked their absolute destruction, their annihilation,
has not the slightest support from Scripture, which always
represents their future as one of conscious suffering enduring
for ever.

The supposition that God will ultimately secure the repentance
and restoration of all sinners is equally unscriptural. There is
not the slightest trace in all the Scriptures of any such
restoration. Sufferings of themselves have no tendency to purify
the soul from sin or impart spiritual life. The atoning death of
Christ and the sanctifying power of the Holy Spirit are the only
means of divine appointment for bringing men to repentance. Now
in the case of them that perish these means have been rejected,
and "there remaineth no more sacrifice for sins" (Heb. 10:26,
27).
