The rich man's last thought flashes to concern for the fate of his five brothers. He utters a final cry to Abraham, begging him to send Lazarus to plead with his brothers to heed his warning testimony. Abraham replies that they had the writings of Moses and the prophets. The rich man, however, thinks his brothers would listen to one from the dead, indicating that he believed in the power of resurrection. Abraham replies that, if they would not follow the Scriptures, they would certainly not be persuaded even by one raised from the dead. These final verses show that Jesus' purpose in giving the parable was to reveal the truth of the resurrection.
Other scriptures tell us what happens where this parable leaves off. Matthew 13:30 speaks symbolically of the wicked being gathered into bundles to be burned. Matthew 3:12 records John's warning to the Pharisees that they would be burned up as chaff if they did not repent. They are to be burned in a fire so hot that no amount of water could put it out because the flames would turn the water to steam. When God punishes the wicked, the fire will be unquenchable. This does not mean, however, that it will not burn itself out when it has no more combustible materials to burn. An unquenchable fire cannot be put out, but it can burn itself out when it has consumed everything. Malachi 4:1, 3 also speaks of this fire, reporting the end of the wicked: They will be ashes and smoke (see Psalm 37:20).
In this, Jesus is preaching the gospel of the Kingdom of God, revealing salvation, the resurrection to eternal life as the gift of God, and inheritance of the Kingdom of God on this earth. Jesus teaches that if we refuse to hear Moses and the prophets—if we refuse to believe the inspired, written Word of God—we have no hope of salvation. All Scripture, the whole Bible containing both the Old and New Testaments, is profitable for doctrine and instruction in receiving the gift of salvation (II Timothy 3:16-17).
