The Book of Revelation explains it all, but too many people are hung up on the ability to not know(2000 years ago, they were not to know), but unless we know at the end how can we be prepared? Rejecting out of hand everything, may prevent the knowledge one could use to be prepared. The whole world has been deceived, by 2 Timothy 3:7
"Ever learning, and never able to come to the knowledge of the truth."
The truth is going to go against even the knowledge of the elect, those secure in their knowledge of God. It is no humans fault, because like Job, Satan was allowed to blind even Job to the truth of what was going on, until the end when God showed Job the truth. If God used a single human, instead of taking over a TV broadcast, to tell the world, even the body of Christ will reject it, because they think they know all truth, but all they know is the Gospel. That is the only thing God told the church to do. Go into all the world proclaiming the Gospel. Teaching others, to go out and do the same thing. When God does send a witness in the end, only those willing to forgo, all their knowledge and wisdom about the end, and trust God, and that witness, will they understand Satan's deception. 2 Timothy 3:7 indicates all knowledge and learning leads to no where. Giving up on knowledge is even harder than understanding the Atonement.
How does one human's understanding help those who think they know everything about how the end happens? It is true that God has used many men of God in the last 100 years to teach the whole council of God. That was done to prepare the hearts and minds of believers to the Truth. It is not the Scriptures that are to blame. It is the world's education system that has hidden the truth and blinded the eyes of the whole world. No one can even refute the teachings of the world and many have tried. They have only had the world's knowledge and understanding to use against the world. If any human has had the truth, they were not allowed to use it. The truth is for the church to be prepared, not the whole world. It is only by Faith, trust in God, that truth can be revealed. And only the Holy Spirit can confirm the truth, in the Word of God, the Bible.
