In eschatology, it is important to remember that almost all Christians agree on these three things:
1) there is coming a time of great tribulation such as the world has never seen,
2) after the Tribulation, Christ will return to establish His kingdom on earth, and,
3) there will be a Rapture—a translation from mortality to immortality—for believers (John 14:1-3;1 Corinthians 15:51-52; 1 Thessalonians 4:16-17).
