Prophecy about what the times will be like before Christs return is all through the bible.
A quick over view. There will be birth pangs. Where all things are coming together. More wars, more earthquakes, more economic upheaval, mens hearts will grow cold, signs in the heavens(remember Jesus star when he was born?) world wide immorality, like in Noah's day...ect. Then one man will rise up, seeming to have all the answers, people will be in fear because of all the bad things happening. Unless they are spiritually prepared through a relationship with Jesus Christ, they will fall for this guy. This man whoever he is, will make a 7 year peace treaty with Israel that he will break in the middle of that 7 years.
You need to have a relationship with Jesus. Get a solid foundation with Him. All these things the bible talks about are going to happen. There isn't a whole lot we can do about those thing. But, we can do something about ourselves, we can prepare as best we can, spiritually, which is top priority, physically and emotionally, and let God do the rest.
