The kingdom of darkness has had its grip on the world for several millennia, but that is all about to come to an end. There is a regime change coming that has been foretold for thousands of years.
It has been prophesied that Jesus will return, and when He does, He will bring an end to Satan's dominion over the earth. The kingdom of darkness will cease to influence mankind as it is destroyed when Jesus begins His reign. He will then establish the kingdom of God on earth and will rule the nations for 1000 years.
But before that takes place, people will be compelled to choose sides. Everyone will have the opportunity to demonstrate who their allegiance is with by the decisions they make. After a time of testing, the decisions are final and the wicked are destroyed as the kingdom of Satan falls. The time to prepare for the coming regime change is now.
