It is interesting that a much higher percentage of people believe in the existence of heaven than believe in the existence of hell. According to the Bible, though, hell is just as real as heaven. The Bible clearly and explicitly teaches that hell is a real place to which the wicked/unbelieving/lost are sent after death.
We have all sinned against God (Romans 3:23). The just punishment for that sin is death (Romans 6:23). Since all of our sin is ultimately against God (Psalm 51:4), and since God is an infinite and eternal Being, the punishment for sin, death, must also be infinite and eternal.
Hell is this infinite and eternal death which we have earned because of our sin.
The punishment of the wicked dead in hell is described throughout Scripture as “eternal fire” (Matthew 25:41), “unquenchable fire” (Matthew 3:12), “shame and everlasting contempt” (Daniel 12:2), a place where “the fire is not quenched” (Mark 9:44-49), a place of “torment” and “fire” (Luke 16:23-24), “everlasting destruction” (2 Thessalonians 1:9), a place where “the smoke of torment rises forever and ever” (Revelation 14:10-11), and a “lake of burning sulfur” where the wicked are “tormented day and night forever and ever” (Revelation 20:10).
The punishment of the wicked in hell is as never ending as the bliss of the righteous in heaven.
Jesus Himself indicates that punishment in hell is just as everlasting as life in heaven (Matthew 25:46).
The wicked are forever subject to the fury and the wrath of God. Those in hell will acknowledge the perfect justice of God (Psalm 76:10). Those who are in hell will know that their punishment is just and that they alone are to blame (Deuteronomy 32:3-5). Yes, hell is real. Yes, hell is a place of torment and punishment that lasts forever and ever, with no end.
