Mat 24:34-34 "Assuredly, I say to you, this generation will by no means pass away till all these things take place. Heaven and earth will pass away, but My words will by no means pass away."
Our Lord Jesus Christ assured us that the whole Endtime Events (up to Rapture) will not last more than a generation.
So the last generation will be able to witness
1. Mat 24:4-5 - False Christ, false christs, etc.
2. Mat 24:6-9 - World War 3,
3. Mat 24:10-14 - Period of Tribulation (Persecutions and Martyrdoms of Christians, Gospel preached to all, rebuilding of temple of God, etc.,
4. Mat 24:15-28 - Great Tribulation,
5. Mat 24:29-31 - Great Heavenly Blackout and Rapture.
Understanding in the last days
Dan 12:4, 9-10 "But you, Daniel, shut up the words, and seal the book until the time of the end; many shall run to and fro, and knowledge shall increase."... Although I heard, I did not understand. Then I said, "My lord, what shall be the end of these things?" And he said, "Go your way, Daniel, for the words are closed up and sealed till the time of the end."
These two thousand years, God has sealed up the Endtime mysteries and He will only reveal it in the last days or last generation.
This Last Generation (LG) series will reveal the spiritual conditions of Endtime Christians, Judgments of God, Preparation of the bride of the Lamb, etc.
