Revelation 13: 7-8 "And Satan was given power to make war with the saints, and to overcome them, and the power was given him over all kindreds and tongues, and nations. And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb, slain from the foundation of the world."
If any person is reading their Bible as they ought, it will equip them to know a lot about what will be seen in the future of this world age. God did not leave us in the dark, it is clear and understandable in your Bible.
A lot of Bible prophesies are being seen right now and the wise will observe, and be warned to know why it is happening. Bible warnings are coming true at an alarming rate, and we should sincerely study them to know.
Satan, as the Antichrist, will be given power to make war with the saints and overcome them. It should be no mystery for us to know why and how this will happen. We are now recognized as a nation of God's people but we are becoming a very evil nation that is turning from God's ways. We are seeing a lot of serious problems that are plaguing our people, and these problems will get much worse unless we see immediate repentance and a return to God's ways.
The world's troubles will become so serious many will turn from God in bitterness. We are now seeing the entire world in a state of helpless confusion that will automatically create a situation to permit Satan as Antichrist to come into our earthly living and it will not be a dark hidden event. Earthly people will see it and many will believe it really is Jesus returning to earth.
Look at LUKE 10:18 where Jesus said, "I saw Satan as lightening fall from heaven." When average people see that as Jesus did, it will be easy to believe Satan as Antichrist is actually Jesus returning to earth but it will be Antichrist, and he will have power to bring a temporary peace to give hope to escape from the world's bitter problems. He will also have power to do great miracles that will further deceive people.
The Bible even state he will deceive the whole world. Antichrist will imitate exactly what Jesus would do until most are deceived, then he will turn into the Satan that he really is and impose the greatly feared tribulation that the Bible describes to be the most disastrous event earthly people will ever have to endure.
And now I will do something I have never done before -- my computer is so loaded it will be inconvenient to look up documenting scriptures, so please do it yourself, such as: 1. The Antichrist will come before Jesus returns and 2. Antichrist will bring tribulation that will be the worse thing earthy people will ever have to endure. The scriptures are easy to find. If you need help--ask me.
