Because it's what Jesus teaches us in Luke 16:19-31,
No, he does not. That is a parable among many....and just because one of the parties has a common name doesn't make it literal.
The rich man represented the Pharisees, who, until the coming of the Messiah were the religious leaders of God's people, yet Jesus did not have a good word to say about them.....he actually condemned them to "gehenna" (Matt 23:33).....which is not "hell" or "eternal damnation" but eternal death. God will not remember them in the resurrection, which is what Jews believed in.
Martha, the sister of Lazarus whom Jesus resurrected, stated what she believed as the destiny of her brother....
"Martha then said to Jesus: “Lord, if you had been here, my brother would not have died. 22 Yet even now I know that whatever you ask God for, God will give you.” 23 Jesus said to her: “Your brother will rise.” 24 Martha said to him: “I know he will rise in the resurrection on the last day.” (John 11:21-23)
What was "the resurrection on the last day" to a Jew? NOT immortality of the soul.
Resurrections were performed by Jesus and his apostles....all were a restoration of human life, not a continuation of spiritual life somewhere else.
Where did Jesus say Lazarus was?
John 11:11-14...
"After he said these things, he added: “Lazʹa·rus our friend has fallen asleep, but I am traveling there to awaken him.” 12 The disciples then said to him: “Lord, if he is sleeping, he will get well.” 13 Jesus, however, had spoken about his death. But they imagined he was speaking about taking rest in sleep. 14 Then Jesus said to them plainly: “Lazʹa·rus has died".
Lazarus was "sleeping".....he had not gone anywhere, and there was no mention of him being in heaven, or he would have wondered why Jesus brought him back to this life, only to die again later from some other cause.
The beggar in Jesus' parable pictured the "lost sheep of the house of Israel" to whom Jesus was sent.....and whom the Pharisees neglected and treated as unworthy of their time and attention. They were spiritually impoverished. Both "died" to their former place and actually changed places.
The "bosom of Abraham" was a position of favor with God...the Pharisees lost it, and the beggar (Christ's disciples) gained it.
How can 'heaven and hell' be in speaking distance of one another? And how can a drop of water on a man's finger cool anyone in a blazing fire? Taken literally, it makes no scriptural sense to a people who had no belief in immortal souls. That notion was adopted later by the Jews and also by Christendom due to pagan Greek influence, not the Bible.
and it's what the Lord teaches thru Apostle Paul in 2 Corinthians 5:8
Wrong again....do you know that there are two resurrections spoken about in the Bible? The "first resurrection" is for Christ's anointed disciples who were promised a role in heaven...ruling with him as "kings and priests"...these alone were promised a heavenly resurrection, but not until Christ's return.
Paul wrote...
"Moreover, brothers, we do not want you to be ignorant about those who are sleeping in death, so that you may not sorrow as the rest do who have no hope. 14 For if we have faith that Jesus died and rose again, so too God will bring with him those who have fallen asleep in death through Jesus. 15 For this is what we tell you by Jehovah’s word, that we the living who survive to the presence of the Lord will in no way precede those who have fallen asleep in death; 16 because the Lord himself will descend from heaven with a commanding call, with an archangel’s voice and with God’s trumpet, and those who are dead in union with Christ will rise first. 17 Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we will always be with the Lord."
Rev 20:6 identifies these ones as "kings and priests" who will reign with Christ for 1,000 years.
Kings need subjects, and priests need sinners for whom to perform their priestly duties.....these will be the ones who come back in the second or general resurrection, spoken about by Jesus...
John 5:28-29...
"Do not be amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice 29 and come out, those who did good things to a resurrection of life, and those who practiced vile things to a resurrection of judgment."
Where does Jesus call these ones from?....their tombs. He cannot raise them from their tombs like he did with Lazarus unless they are all still in them. The dead are not conscious...(Eccl 9:5, 10)...which is why death is likened to a sleep.....one from which only God's spirit can awaken a person....and he has promised to do so. (Acts 24:15)
Only cults teach soul sleep since they don't go by what Jesus teaches us.
Only "weeds" teach what Jesus never did....Jesus said that Lazarus was "sleeping"...not that he was somewhere else in spirit form.
He brought him back to this life and reunited him with his family and friends. He did the same to Jairus' daughter, and the widow's son.
These are promised the second resurrection under the Kingdom's rulership....when death would inevitably take them again.
The thief hung alongside Jesus will likewise "be with Jesus in Paradise"....not heaven.
When you see soul sleep being taught by any group, you can expect other error to be taught as well.
When I see an immortal soul suggested, or that all Christians are going to heaven, I shake my head and wonder if the people who believe that have ever read a Bible in their lives....if all you know is church "theology", then you are in the same category as the Jews were, under the teachings of the Pharisees, which Jesus called "leaven"... teaching that were corrupted by men way back and deeply entrenched. (Luke 12:1; Matt 16:11-12; Matt 15:7-9)
When did God ever say that earth was a training ground for heaven? God designed us humans for everlasting life here on earth...I don't see where he ever changed his mind on that. All God did was organize a class of Jesus' faithful disciples to rule over redeemed mankind with his son...the one he appointed as King of his Kingdom. Jesus and his anointed ones will have many subjects, bringing them back to God's original purpose for the human race....(Rev 21:2-4)...everlasting life in Paradise on Earth.
