Where in the bible does it say that people go to heaven or hell after death?

How about Jesus' words to the thief on the cross?

"Today you shall be with me in paradise." Luke 23:43

Parables are just that -- parables!

Old Testament quotes speak of the state of the soul after death under the old covenant (before the resurrection of Christ.)

It does not say anything like that.

For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. EX 9:5.

So, just how did the misinterpretation happen? Spiritualism, that is how. Pagan religions teach that we have an immortal soul but the Bible teaches that we do not have one. Their teaching is 'pleasing to the ear' of those who want to still believer their pagan beliefs and at the same time be able to call themselves Christian. Which makes them false Christians.

Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Matt 7:21.

Paul told us in 2 Corinthians 5:8 "We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord." (The Lord is in Heaven.)

Luke 16:22-23 "And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried; And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom."

There is no heaven or hell.
