What will happen on the day of judgment? According to the Bible ...

What is the definition of doomsday in the Bible? When it will arrive? What will happen when it arrives? Are Christians judged at a different time than non-believers?
According to the first book of Peter, a type of doomsday has already begun for Christians during this life. It is long before the day of Jesus' second coming and the resurrection of the dead.

Because the time has come for the judgment to begin with the family of God; and if it starts with us for the first time, what will be the end of those who do not obey the gospel of God? (1Peter 4:17, HBFV everywhere unless otherwise indicated)

To be more specific, what is the type of assessment that begins with God's family? Does verse 17 of 1 Peter 4 refer to the sufferings and trials that Christians have in this life or to a still future day of judgment (see Revelation 20:11 - 15)?

In the verses immediately preceding verse 17, Peter tells Christians to endure their trials in life with a good spirit. The context indicates that God's judgment is now based on believers, while judging how we react to our trials and trials in life, especially those that are not self-inflicted or deserved.

The judgment in 1 Peter and elsewhere in the New Testament mainly refers to the process of evaluating a person's behavior from the moment he is converted to the time he dies.

What a Christian does during his life determines the outcome of their eternal life to come, how high or low their position in the kingdom of God will be, and so on.

Furthermore, if trials, tests and suffering break our faith and make us give up following God's lifestyle as a result, we cannot be saved and we will wait for our fate on the day of judgment. For those who are truly Christians, what they do during this life determines how our Heavenly Father will later "condemn" them.

Faith and obedience
To be more theologically precise, although faith is fundamental to entering the Kingdom, obedience or good works are needed to determine what the rewards and responsibilities of each will be in that kingdom (1 Corinthians 3:10 - 15).

If someone does not have good works, but claims to have faith, that person is not "justified", since he does not have an effective and saving faith that will bring him into that kingdom (James 2:14 - 26).

Since the very limited number of true Christians called during this present life, their "day of judgment" has already begun, since their levels of faith and obedience exercised in this life will determine their eternal state (see Matthew 25:14 - 46 , Luke 19: 11 - 27).

Although judged during their earthly life, Christians will still stand before Christ to account for what they have done. The apostle Paul wrote about it when he declared that we would all be standing before the seat of God's judgment (Romans 14:10).

It should be noted that there are several texts in which God first begins the judgment or punishment for sin with His people (see Isaiah 10:12, Ezekiel 9: 6, cf. Amos 3: 2). This is especially true in the book of Jeremiah, since at that time Judah was to be punished before Babylon and the other nations surrounding the Holy Land (see Jeremiah 25:29 and chapters 46 - 51).

Humanity before God
The largest general period of judgment is described as having occurred after the turn of the millennium.

And I saw the dead, small and large, standing before God; and the books were opened; and another book was opened, which is the book of life. And the dead were judged by the things written in the books, according to their works (Revelation 20:12).

People in this resurrection can still be saved, which is a wonderful truth that will surprise many who believe that most of the dead go to hell on the day of their death.

The Bible teaches that the vast majority of humanity, who have never had the full chance of being saved during this life, will receive the first opportunity to be saved after being resurrected (cf. John 6:44, Acts 2:39, Matthew 13: 11-16, Rom 8:28 - 30).

When those who were never called or converted died, they did not go to heaven or hell, but simply remained unconscious (Ecclesiastes 9: 5 - 6, 10) until the end of the millennium of Christ's dominion over the earth. For the "unwashed masses" in this second resurrection (Revelation 20: 5, 12-13), they will receive a period of several years to repent and accept Jesus as Savior (Isaiah 65:17, 20).

The Bible reveals that the first "doomsday" of Christians is the period from their conversion to physical death.

For the countless billions of humans (past, present and future) who live a physical life without a full chance of understanding the gospel, who are never "enlightened" and "taste the good Word of God" (Hebrews 6: 4 - 5 ), their doomsday and showdown is still future. It will begin when they rise and come before the Great White Throne of God (Revelation 20: 5, 11 - 13)
