The movie is about the endtimes prophesied in the Bible
The movie is about the events that can be expected in the endtimes. The events that occurred in the film are the type of events that will occur during the endtimes. Some of the events that have already occurred were shown to illustrate how they will devastate people. The attack on the WTC, floods, typhoons, tornados, missing people, etc, are symbols of what people can expect during the endtimes. They are shown so that people can relate with them, so that people will feel and understand how the people living during the endtimes will feel and understand.
The movie is a Christian movie. If someone isn't a Christian, the movie will not only have nothing that they can relate to but it will make them angry and dissatisfied, and they will complain about it and insult it because they don't understand the message that it offers. It's a simple message, so simple that a child can understand it, and that's the stumbling block for non-Christians.
The message is: accept Jesus Christ as your Savior and Lord. Put your faith in him. He has died for your sins so that you don't have to. Because of him, you can enter into the Kingdom of Heaven. There's nothing else you have to do. Some peopole will accept him and others won't. Some people believe in the Christian God and others don't. Some people believe in God but not in Jesus Christ. Some people believe in other Gods. Some people believe the prophesy of the Bible and others don't. The Scriptures have been debated for thousands of years and will be debated until the end of time. Some people believe that the endtimes are upon us and others don't. Everybody has the free will to choose what they want to believe. The Bible says that the end will not come until the Gospel is preached to all the world. It either has or soon will be.
