Rev.19[1] And after these things I heard a great voice of much people in heaven, saying, Alleluia; Salvation, and glory, and honour, and power, unto the Lord our God:

Yeshua said there are people in heaven:

Matt.11[11] Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he.

Luke.7 28] For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: but he that is least in the kingdom of God is greater than he.

Matt.5 [19] Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least " in ", (which means by, among ) kingdom of heaven: but whosoever shall do and teach them, the same shall be called great " in ", (which means by, among ) the kingdom of heaven

2Kgs.2 [1] And it came to pass, when the LORD would take up Elijah into heaven by a whirlwind, that Elijah went with Elisha from Gilgal.

[11] And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and parted them both asunder; and Elijah went up by a whirlwind into heaven.

Here a a few scriptures:

Luke.23 [39] And one of the malefactors which were hanged railed on him, saying, If thou be Christ, save thyself and us.
[40] But the other answering rebuked him, saying, Dost not thou fear God, seeing thou art in the same condemnation?
[41] And we indeed justly; for we receive the due reward of our deeds: but this man hath done nothing amiss.
[42] And he said unto Jesus, Lord, remember me when thou comest into thy kingdom.
[43] And Jesus said unto him, Verily I say unto thee, To day shalt thou be with me in paradise.

People in Hell today

Luke.16[19] There was a certain rich man, which was clothed in purple and fine linen, and fared sumptuously every day:
[20] And there was a certain beggar named Lazarus, which was laid at his gate, full of sores,
[21] And desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores.
[22] 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;
[23] And in hell he lift up his eyes, being in torments , and seeth Abraham afar off, and Lazarus in his bosom.
[24] And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame .
[25] But Abraham said, Son, remember that thou in thy lifetime receivedst thy good things, and likewise Lazarus evil things: but now he is comforted, and thou art tormented.
[26] And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence.
[27] Then he said, I pray thee therefore, father, that thou wouldest send him to my father's house:
[28] For I have five brethren; that he may testify unto them, lest they also come into this place of torment.
[29] Abraham saith unto him, They have Moses and the prophets; let them hear them.
[30] And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent.
[31] And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.

1Pet.3[ 19] By which also he went and preached unto the spirits in prison; [20] Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
