Question concerning Hell on FB: “If when you die you go to heaven or hell what is the purpose of judgment Day?”
Those who have trusted in Jesus Christ for the remission of sin, at the moment of death, they are translated directly into the presence of our Lord in a disembodied, spiritual, state…fully conscious, fully aware, fully interactive, awaiting the resurrection of the righteous (2 Corinthians 5:8; Acts 24:15; John 5).
Hell is not currently occupied by human kind (only the most horrific of demons/angels – Jude 1:6) as Hell was created specifically for the Devil and his rebellious angels (Matthew 25:41). Mankind will enter Hell by choice, not mandate.
Those who die rejecting the mediation for sin only available through faith in Jesus as Lord (John 3:16-18); these, at the moment of death are translated to Sheol-Hades/Torments in their disembodied state, fully aware, fully conscious, and they will remain there until the resurrection of the condemned (Luke 16; John 5:29).
The resurrection of the condemned will manifest prior to the Judgement of the Condemned (Great White Throne Judgment) manifesting at the end of Messiah’s Millennial Reign (Rev 20:11-15). The resurrected rebellious/condemned will receive a resurrected body of corruption and stand before Jesus Christ to be judged according to their works and they will be found guilty of sin and that sin cannot be permitted to enter the Kingdom (Rev 21:27); therefore, they will receive sentencing/adjudication and ultimately die the “second death” subsequent to suffering commensurate to the sin committed in the body while constrained by Time and physics.
Hell/the Lake of Fire/Gehenna will be a place of suffering and ultimately death, a cessation of all life, for all of mankind who has rejected God the Father by rejecting faith in Jesus as Lord; why Hell?
The sin of mankind will not be permitted to enter the New Jerusalem nor will sin be tolerated in the presence of our Holy God (Revelation 20:11-15). The Devil, the fallen angels, the Beast, the False Prophet, will all suffer eternally in Hell as it is the Devil and his rebellion that is causation for the creation of Time, our Universe, the human genome, in order deal with that rebellion apart from the Kingdom where nothing impure is permitted to enter or exist (Rev 20:10; 21:27).
