The Christian concept of hell comes from the Bible. Here is an example spoken by Jesus in Matthew 13:
Then he [Jesus] left the crowd and went into the house. His disciples came to him and said, "Explain to us the parable of the weeds in the field."
He answered, "The one who sowed the good seed is the Son of Man. The field is the world, and the good seed stands for the sons of the kingdom. The weeds are the sons of the evil one, and the enemy who sows them is the devil. The harvest is the end of the age, and the harvesters are angels.
"As the weeds are pulled up and burned in the fire, so it will be at the end of the age. The Son of Man will send out his angels, and they will weed out of his kingdom everything that causes sin and all who do evil. They will throw them into the fiery furnace, where there will be weeping and gnashing of teeth. Then the righteous will shine like the sun in the kingdom of their Father. He who has ears, let him hear."
Some will say that this description is not literal, but we have no reason to believe from anything else the Bible says that it is not literal.
The Bible teaches that there is a heaven and there is a hell. God is a God of love but also of justice. Those who do not believe that his son Jesus was sent to save people from sin and eternal death in hell will be sent to that place of punishment for their disbelief. People who end up there have no one to blame but themselves. On the other hand, people who end up in heaven have no one to credit but God.
The "concept of hell" DOES NOT "come from the "Bible" as has been said, let me show you first of all where the concept comes from--
The meaning given today to the word “hell” is that portrayed in Dante’s Divine Comedy and Milton’s Paradise Lost, which meaning is completely foreign to the original definition of the word. The idea of a “hell” of fiery torment, however, dates back long before Dante or Milton.
The Grolier Universal Encyclopedia (1971, Vol. 9, p. 205) under “Hell” says: “Hindus and Buddhists regard hell as a place of spiritual cleansing and final restoration. Islamic tradition considers it as a place of everlasting punishment.” The idea of suffering after death is found among the pagan religious teachings of ancient peoples in Babylon and Egypt. Babylonian and Assyrian beliefs depicted the “nether world . . . as a place full of horrors, . . . presided over by gods and demons of great strength and fierceness.” Although ancient Egyptian religious texts do not teach that the burning of any individual victim would go on forever, they do portray the “Other World” as featuring “pits of fire” for “the damned.”—The Religion of Babylonia and Assyria, by Morris Jastrow, Jr., 1898, p. 581; The Book of the Dead, with introduction by E. Wallis Budge, 1960, pp. 135, 144, 149, 151, 153, 161, 200.
Now as for it being taught in the Bible--The word “hell” is found in many Bible translations HOWEVER In the same verses other translations read “the grave,” “the world of the dead,” and so forth. So hell is not "burning", hell is the common grave, nothing more.
“Much confusion and misunderstanding has been caused through the early translators of the Bible persistently rendering the Hebrew Sheol and the Greek Hades and Gehenna by the word hell. —The Encyclopedia Americana (1942), Vol. XIV, p. 81.
Is a fiery hell taught anywhere in the Bible? Today, many scholars in Christendom would answer no. The New Catholic Encyclopedia states: “In the final analysis, the Catholic doctrine on purgatory is based on tradition, not Sacred Scripture.” Regarding hell, A Dictionary of Christian Theology comments: “In the N[ew] T[estament] we do not find hell fire to be a part of the primitive preaching.”
In fact, the doctrine commission of the Church of England recently made headlines when it recommended repudiating the teaching of hellfire altogether. Dr. Tom Wright, dean of Litchfield Cathedral, states that past imagery of hell “made God into a monster and left searing psychological scars on many.” The commission’s report describes hell as “total non-being.” Similarly, the New Catholic Encyclopedia notes regarding the Catholic view: “Theology today approaches the problem of hell from the angle of separation from God.”
Actually, what the Bible teaches about the soul conflicts with the teachings of purgatory and hellfire. The Bible often speaks of the death of souls. “The soul that is sinning—it itself will die.” (Ezekiel 18:4; compare the King James and Catholic Douay versions.) According to the Bible, the dead are unconscious, unable to feel pain. “The living are conscious that they will die; but as for the dead, they are conscious of nothing at all.” (Ecclesiastes 9:5) The hope that the Bible holds out for the dead is that of a future resurrection. When Jesus’ friend Lazarus died, Jesus compared death to sleep. Lazarus’ sister Martha expressed the hope taught in the Bible when she declared: “I know he will rise in the resurrection on the last day.” By raising Lazarus from the dead, Jesus confirmed that hope for mankind.—John 5:28, 29; 11:11-14, 24, 44.
Would we as parents stick our childs hand in a fire if he did something wrong, surely not, then why should we attribute such a thing to God.
