All will go to heaven. Not everyone shall enter.
You can be kicked out of heaven. Just as Satan was kicked out.
And he said unto them, I beheld Satan as lightning fall from heaven. Luke 10:18
John 5:22-23,25,27-30 KJV
[22] For the Father judgeth no man, but hath committed all judgment unto the Son: [23] That all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him. [25] Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live. [27] And hath given him authority to execute judgment also, because he is the Son of man. [28] Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, [29] And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation. [30] I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.
Luke 13:24 Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able.
Matthew 7:21-23 KJV
[21] 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. [22] Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? [23] And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Psalm 31:23 KJV
[23] O love the Lord, all ye his saints: for the Lord preserveth the faithful, and plentifully rewardeth the proud doer.
Revelation 20:4-7 KJV
[4] And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years. [5] But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection. [6] Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years. [7] And when the thousand years are expired, Satan shall be loosed out of his prison,
Revelation 20:11-13,15 KJV
[11] And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. [12] And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. [13] And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. [15] And whosoever was not found written in the book of life was cast into the lake of fire.

[21] He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.

[15] So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. [16] He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep. [17] He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
