I don't think Luke 16 has anything to do with the afterlife. I think it is a warning to the Jews of what is going to happen to them.
But Luke 16 specifically says the begger and the rich man
died, and the rich man
buried. Yes, what is going to happen to them
AFTER THEY DIE! Luke 16:22!!
Yes, I believe it's an analogy. Look at Jesus's parables, look at the parable of the Talent, the master goes away and give his servants a certain amount of money.
14 For
the kingdom of heaven is as a man travelling into a far country,
who called his own servants, and delivered unto them his goods.
15 And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey.
16 Then he that had received the five talents went and traded with the same, and made
them other five talents.
17 And likewise he that
had received two, he also gained other two.
18 But he that had received one went and digged in the earth, and hid his lord's money.
19 After a long time the lord of those servants cometh, and reckoneth with them.
20 And so he that had received five talents came and brought other five talents, saying, Lord, thou deliveredst unto me five talents: behold, I have gained beside them five talents more.
21 His lord said unto him, Well done,
thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
22 He also that had received two talents came and said, Lord, thou deliveredst unto me two talents: behold, I have gained two other talents beside them.
23 His lord said unto him, Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
24 Then he which had received the one talent came and said, Lord, I knew thee that thou art an hard man, reaping where thou hast not sown, and gathering where thou hast not strawed:
25 And I was afraid, and went and hid thy talent in the earth: lo,
there thou hast
that is thine.
26 His lord answered and said unto him,
Thou wicked and slothful servant, thou knewest that I reap where I sowed not, and gather where I have not strawed:
27 Thou oughtest therefore to have put my money to the exchangers, and
then at my coming I should have received mine own with usury.
28 Take therefore the talent from him, and give
it unto him which hath ten talents.
29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
(Mat 25:14-30 KJV)
Here Jesus uses a story to tell them how the kingdom works. He isn't really giving them money. I believe Luke 16 is a story telling the Jewish leaders that they are going to be the ones who are cast out. The preceding chapters will give you context. However, take notice that Jesus is addressing the Pharisees. It doesn't make sense the Jesus would stop right in the middle of His discussion and teach about the afterlife and then go back to addressing the Pharisees. however, if the Luke 16 is a parable about the Jews it makes sense. Remember what Mark said,
33 And with many such parables spake he the word unto them, as they were able to hear
it.
34 But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples. (Mar 4:32-34 KJV)
