There are many teachings about the final judgment. Some teach there will be no judgment at all. Most people believe this because the evidence of their lives shows no concern for a judgment. Some think that it is going on now. In a way they are correct because everything we do effects our final judgment, and then the day of the Lord will be more of a sentencing or declaration day than one of judgment (as we understand the word). A few people teach that the judgment has already passed, and this teaching confuses people. If there is no judgment to come, why do people live by strict rules and try to convert people to their beliefs?
Despite all the error and false teaching about the final judgment day, we must recognize that the Bible is certain of its coming. Wicked angels are awaiting judgment (2 Peter 2:4) There are passages all through the pages of the Bible that speak of a final judgment. The wicked need to fear the judgment because the wrath of God will be upon them (Romans 2:8), but the righteous look forward to that great day when God will reward them with eternal life in heaven (Romans 2:7).
We do not know when this will take place for only God knows that time, we can be assured of this from the pages of the Bible; All will die and after that each will face their judgment (Hebrews 9:27). This final judgment will come unexpectantly, like a thief in the night (Matthew 24:36; 2 Peter 3:10). Acts 17:30-31 tells us that God has appointed A DAY in which He will judge the world. Everyone will be judged. Almighty God will judge each individual. The standard of Judgment will be the life that was lived and the actions of the person living that life. Jesus Christ will be the great Judge. God will judge the earth through Christ.
We also know that God keeps records in heaven. He writes down the names of the righteous into the Lamb's Book Of Life, and he also records the names of those who rebel against Him. Here are some of the things for which we will be judged: Our thoughts (Proverbs 23:7: 2 Corinthians 10:5); Secret things (Romans 2:6); Every work (Ecclesiastes 12:13-14); Our words (Matthew 12:36-37); All we have done (1 John 3:4; Galatians 6:7-8); and what we have failed to do (James 4:17). This last one should be the most sobering thought that comes into our mind every day we live.
We know that God's judgment will be true, just, righteous, and everybody will be treated fairly and justly, and everyone will get what they deserve. There will be no appeals process, because there will be no error in judgment by the perfect God. Prepare to meet thy God.
