No date is given for this; in fact, we are told that we must not set dates. But the Bible gives signs of the time in which this will happen. I list some of them here:
1. There will be wars and rumours of wars (Matt 24:6, 7).
2. There will be famines, pestilences and earthquakes (Matt 24:7).
3. Travel and knowledge will increase (Dan 12:4; 2 Tim 3:7, 8).
4. We may expect to see materialism and blatant homosexuality (Luke 17:26 - 30; Gen 19: 4, 5).
5. People will be selfish, disobedient, unthankful, unholy, lovers of pleasure more than lovers of God (2 Tim 3:1 - 4).
6. Israel will be back in her land (Mark 13:28, 29).
7. Many will be deceived by false prophets and false teachers. Many will fall away from the true faith, and Christians will be persecuted (Matt 24:4, 5, 11; 2 Pet 2:1, 2; 1 Tim 4:1 - 3; 2 Pet 3:3 - 7; Jude 17, 18; Mark 13:9; Luke 21:12 - 18).
There will be a time of great suffering on the earth known as the Tribulation, the Great Tribulation or "the time of Jacob's trouble" (Matt 24:21, 22). But before that happens, all those who belong to Jesus will be taken up and will escape the terrible things that are to come (You can read about that at 1 Thess 4:13 - 18; 1 Cor 15:51 - 54 and Phil 3:20, 21).
We need to be ready against that day.
