The Bible is clear that it will be impossible for humans to sin in heaven. A close look at Revelation 21 and 22, the New Testament's final chapters, offers several insights that indicate sin will no longer remain in the new heaven in eternity future.
Will it be possible to sin in heaven? Will people in heaven be able to sin?
Revelation 21:4 notes the future removal of any pain or problems: "He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore."
This same verse notes the reason there would no longer be death or pain: "for the former things have passed away." The new heaven and new earth will exist without the curse of sin found in this world.
The description of the new heaven and heavenly city includes an absence of sin. Revelation 21:27 states, "But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb's book of life."
Revelation 22:3 states, "No longer will there be anything accursed." The curse of sin that entered humanity with Adam and Eve in the Garden of Eden in Genesis 3 will be removed.
The focus will be God and worship of Him. Revelation 22:3 continues, "but the throne of God and of the Lamb will be in it, and his servants will worship him."
Revelation 22:14-15 contrasts the holy ones in God's presence with the sinners who live outside: "Blessed are those who wash their robes, so that they may have the right to the tree of life and that they may enter the city by the gates. Outside are the dogs and sorcerers and the sexually immoral and murderers and idolaters, and everyone who loves and practices falsehood." These evil ones have no ability to enter into the sinless presence of the Lord in this future eternal state.
Revelation 22 concludes with the author John proclaiming, "Come, Lord Jesus!" (Revelation 22:20). He longed for a future time when sin would be no more.
Scripture provides a clear conclusion that there will be no sin in heaven. Our bodies will be different, the curse of sin will be removed, and we will be in direct access to God's presence as believers. The focus will be on the worship and glory of God.
