"But I say to you that every idle word, whatever men may speak, they shall give an account of it in Judgment Day." (Matthew 12:36), solemn words from the mouth of Jesus. There is certainly a day of judgment planned, but is it in the future or is it every day, every moment? However, we do know judgment will have already past when Christ descends at His second advent, "And behold, I am coming quickly, and My reward is with Me, to give to each as his work is." (Revelation 22:12). We also know records are being kept of every word and every action, "I call Heaven and earth to witness against you today that I have set before you life and death, the blessing and the curse. Therefore choose life that you may live, you and your seed." (Deut. 30:19), these are the words of Moses to the Israelites and "A stream of fire went out and came out from before Him. A thousand thousands served Him and a myriad myriads stood before Him. The court was set and the books were opened." (Daniel 7:10). From Daniels vision, it appears that this is a particular time and it is taking place in Heaven because of those that are looking on this event and the ones serving the Judge are God's angels and of course, Christ, certainly is acting as our Advocate, thank God.
What seems correct is that those being judged, each of us, will not be present at this court setting, only the books of our accounts, which are purely accurate and no defense can be given by us that isn't already known, God's records are complete. John brings more light on this, "And I saw the dead, the small and the great standing before God. And scrolls were opened. And another scroll was opened, which is the Scroll of Life. And the dead were judged out of the things written in the scrolls, according to their works." (Revelation 20:12). The word for standing in Strong's dictionary: "histemi" has a list of meaning and standing is the general meaning but can refer to be literal or figurative. Since the dead are not to rise again until they are called to the resurrected, I consider this to mean figurative. This speaks only of the dead being judged by their accounts in the books (scrolls). Not only were the books of their accounts opened but the Book of Life was also opened, those already judged and listed, according to Christ, and the living have not yet been judged.
We still don't know when this court takes place but I can assume it ends when
the last person is judged and sealed, either way, "Do not harm the earth, nor the
sea, nor the trees, until we seal the slaves of our God on their foreheads." (Revelation
7:3), "The one acting unjustly, let him still act unjustly; and the filthy, let his
still be filthy; and the righteous, let him still do righteousness; and the holy,
let him still be holy." (Revelation 22:11). Does the Bible declare when judgment
day starts? I would logically assume it is sometime after Christ had established
salvation for His Father, Jehovah. Maybe a starting point could be at the end of
However, sins are still sins, and the earth needs to be cleansed, as the sanctuary was cleansed once a year, this is still left to occur for earth and its inhabitants, indicating that possibly the courts in Heaven have started this process with its judgments and when the last soul is judged and sealed, Christ will come again and complete this task. Judgment still has a task to complete. After Christ second advent, a thousand year period starts, when the saints, those resurrected and those succeeding through the tribulation period, will spend this time with Jesus and they will have the opportunity to judge for themselves from God's records those that were found wonting and the angels that worked for Satan in order to understand why they were judged as they were and to understand that God had every just reason for His judgments. The scapegoat, at the end of the thousand years will be Satan and the sea of fire will be the end of Satan and death and also for those not found in the Book of Life, completing the testing period, where we currently exist. Judgment day will take place for those that have passed on into what Christ called, a sleep, referring to the first death, the second death occurs in the lake of fire along with Satan and death. This is a topic not to be uncertain about. Christ died for the purpose of you avoiding this day of His sentencing, because you are written in the Book of Life. God Jehovah made available to all, this reward of eternal life through His Son's sacrifice and it is our decision and responsibility, to make our decision to follow Christ, whom He sent to show us the way to God's salvation. This is a onetime offer, executing right now, before our first death. As Christ said, his burden is light and He promises to help in every way but it is our journey and our efforts, choose wisely.
