We deny our sin...but there's a book:
Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. And if anyone's name was not found written in the book of life, he was thrown into the lake of fire. - Revelation 20.11-15
Let's not foolishly pretend we're good. Let's confess we're bad and receive Jesus' goodness on our behalf. He'll have our sin written on Him (2 Cor. 5.21). And have our names written in the book of life.
