Revelation 20:11-15
Then I saw a great white throne and him who was seated on it. Earth and sky fled from his presence, and there was no place for them. And I saw the dead, great and small, standing before the throne, and books were opened. Another book was opened, which is the book of life.The dead were judged according to what they had done as recorded in the books. The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what he had done. Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. If anyone's name was not found written in the book of life, he was thrown into the lake of fire.
How would one know if his or her name is found written in the book of life? No one knows except the One who gives life Himself. What is this life? Is it just the ordinary life we live on earth? No, it is eternal life in Christ. He is that life-giver. There is no one else in whom we can find eternal life. He is the Way, the Truth and the Life. He who has the Son has this eternal life in him or her because only He has that eternal life in Him. This eternal life passes the second death. There is no second death to those who have this eternal life. Death and Hades were thrown into the lake of fire. What does that mean? If you have Christ in you, there will be no death in you. The death we are talking about here is the second death. The first death is for the presence of the first Adam in you. The second death is for the absence of the Last Adam in you. The Last Adam is the Lord Jesus Christ and He is the Eternal One, not the first Adam.The first Adam could not eat the fruit of the Tree of life in the garden of Eden. He was together with Eve and the Devil, locked out of that garden.
How does the first death affect the second death in you? If you do not put to death the sinful nature of the Devil in you, there will be no Christformation in you. Those without Christformation in them will be thrown into the lake of fire. Death and Hades are reserved for those who still have the sinful nature of the Devil in them. First they die the natural death like anyone and now the second death. But, before that, the fair and just God will judge everyone based on their obedience to everything Christ, His beloved Son had commanded on Earth. There will be no excuse or reason for you to say that you do not know what He had commanded on Earth. So, your deliberate rebellion towards God and your stubbornness in continually obeying the sinful nature of the Devil in you instead of Christ, will earn you the second death. God is a fair and just God. So, you should put to death the first Adam completely in you and let the Last Adam be formed in you permanently. The first Adam was the one who brought the sinful nature of the Devil in you. First death came about because of the first Adam and now, the second death will come if you do not have the Last Adam formed in you permanently. There is a just judgment waiting for all of us at the end of everything. Not the kind of unjust judgments of man we see today, but from the just and fair God who has everything we do on Earth recorded in His presence. It doesn't seem like that to you, right? But, it does!
Revelation 21:8
But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars--their place will be in the fiery lake of burning sulfur.This is the second death."
