""And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh." Luke 21:20
There are hundreds of prophesies in the Bible. Some of the prophesies are from the prophets, some from God in the Old Testament and some from Jesus. There is much controversy concerning modern prophesies. But concerning prophesies in the Bible, there should be no controversy or question. On many issues the Bible tells forth what will happen based on God having seen the outcome in advance. It's not that God makes these things happen, God sees the things happen, good and bad that mankind does to itself.
God tells what He sees and that is prophesy. There should be no question at all that if the Bible says such an event will happen, it will happen, and if the event happening is the same event spoken of in the scripture, it will be conspicuous and raise no doubt in the heart of the believer. The above event is going to happen and many other events that precede this event are going to happen. God told us about the events so that those who are following His plan can be prepared.
I would say that in most cases those who are prepared have a greater chance of receiving a benefit from opportunities that arise in life. Just the same those who are prepared have a better understanding of the events in our lifetime that were spoken of in the Bible. God doesn't tell us what is going to happen so we can go around acting like we know something that someone else doesn't. It is so that we can always be operating in the will of God, cooperating and co-creating with God as the prophesies of the scripture unfold. Isn't that what you do for your own children? How much so God for us. Don't be afraid to understand the events spoken of in scripture as you see the signs of them approaching. They were written to enlighten you, benefit you and protect you.
