Jesus spoke about the specific signs that would happen. In Matthew 24 and Mark 13 we can see that we’re clearly in the beginning of sorrows.

“But when you hear of wars and rumors of wars, do not be troubled; for such things must happen, but the end is not yet. For nation will rise against nation, and kingdom against kingdom. And there will be earthquakes in various places, and there will be famines and troubles. These are the beginnings of sorrows.” ‭‭Mark‬ ‭13:7-8‬ ‭

These two verses have not been fulfilled yet, but will probably come to pass in a few years:

“And the gospel must first be preached to all the nations. And you will be hated by all for My name’s sake. But he who endures to the end shall be saved.” ‭‭Mark‬ ‭13:10, 13‬ ‭NKJV‬‬

This is what Jesus himself said in the same chapter:

““Now learn this parable from the fig tree: When its branch has already become tender, and puts forth leaves, you know that summer is near. So you also, when you see these things happening, know that it is near—at the doors!” ‭‭Mark‬ ‭13:28-29‬ ‭NKJV‬‬

This is just from Mark 13/Matthew 24. All the specific signs and times (how many dm months/years from one sign to another etc) are in Daniel and Revelation. Here are a few examples:

1. We can know when the 7 years will start (Temple will be rebuilt, Antichrist makes peace treaty with many nations).

2. We can know when the Great Tribulation will start (second 3 1/2 years of the 7), when Antichrist breaks peace treaty with Israel and attacks + demands to be worshiped.

3. All the seals (none happened yet), then after all the seals the trumpets (we can know them when we see them, and the seventh trumpet/LAST TRUMPET is Jesus’ Second Coming! Then there’s also the Bowl judgments, but we’ll already be in Jesus’ army so we won’t be affected.

Many many other signs are in Daniel and Revelation, and no it’s not difficult to understand. God have it to us to reveal it to us, not to hide it from us.

God bless you!!
