Read Revelation 20.
This chapter is where we get the doctrine of the Millennium. The word “millennium” is Latin for “one thousand years,” the exact period of time that verse 2b says Satan will be bound. During this one thousand year period, those who were martyred during the Great Tribulation were resurrected (v. 4) and “reigned with Christ a thousand years” (vv. 4, 6).
No Christian likes the idea of being persecuted for Christ; being “beheaded” for him is a gruesome and terrifying concept. Yet, verse 6 says, “Blessed and holy are those who share in the first resurrection” (which is the one described in verses 4-5). The reason they are blessed is that “the second death has no power over them.” Their faith in Christ stood the test of persecution and even martyrdom which demonstrated that it was genuine. Therefore, they are safe forever from the “second death” and, in fact, “will be priests of God and of Christ and will reign with him for a thousand years.”
In contrast to this resurrection, verses 11-15 describe the general resurrection of the rest of mankind (v. 13). These people did not reign with Christ; they were judged by him for how they lived during their time on this earth. (v. 13: “each person was judged according to what they had done”). But notice that the result of this judgment was not based on what they had done; rather, “Anyone whose name was not found written in the book of life was thrown into the lake of fire” (v. 15). God will judge every sinner at the judgment of the dead and he will describe the reasons why they deserve to be in the lake of fire based on their works. But those who escape that judgment do not escape it because they had good works. Instead, those who escape the lake of fire did so because they were found in the book of life.
This is the gospel; this is the central truth of our faith. An impartial judgment of our works by a just God would ensure that every one of us would be a goner. But God, in his grace, chose some of us–not because of our works but simply because he is gracious. He wrote our names in his book of life so that we would escape this judgment. But, so that he would not be unjust for forgiving us, he sent Christ to pay the penalty for our sins.
If you’ve been reading these devotionals over the last year, it seems very likely to me that you’ve trusted Christ and are following him. But it is possible that you haven’t done that or that you found this page on our website through some other means. Do you understand that, on your own, you have no basis on which God should allow you into his presence after this life is over? You may be a very good person relative to many other people but compared to God, all of us are wicked, fallen, and completely deserving of eternity in a lake that burns with fire.
Do you understand that Christ came into the world to save sinners from this lake of fire? Have you come to God at some time in your life and put your faith fully and only in Jesus Christ? If not, please cry out to God for mercy and ask him to save you because of Jesus’ death on the cross for you.
If you have trusted Christ, remember that God has an incredible, eternal future waiting for you. Whatever problem you face in life today, whatever price you pay for following him will be forgotten when you serve him and reign with him forever. Take hope in that!
