Final answer:
The Rapture is an event in Christian eschatology where, after the dead in Christ rise, those who remain will ascend to heaven. It is associated with the Second Coming of Christ and the Last Judgment.
Step-by-step explanation:
The event described where 'the dead in Christ will rise first, then those who remain' is commonly known in Christian eschatology as the Rapture, an event associated with the Second Coming of Christ and the end of the world. After the dead in Christ rise, it is believed that those who remain will ascend to heaven. This is part of a broader religious narrative surrounding the Last Judgment, where Christ returns to judge all of mankind, separating the blessed who will ascend to heaven from the ones who will go to hell. In Christian art and texts, this moment is often depicted with Christ in the center, distinguishing the righteous from the wicked, reflecting the belief in salvation and the final reconciliation with God for believers.
