Josh Wheaton (Shane Harper), a Christian college student, enrolls in a philosophy class taught by Professor Jeffrey Radisson (Kevin Sorbo), an atheist, who demands that his students sign a declaration that "God is dead" to get a passing grade. Josh is the only student in the class who refuses to sign and is then required by Radisson to debate the topic with him, with the class members deciding who wins. via Wikipedia
Here's my favorite scene.
Mark: You prayed and believed your whole life. Never done anything wrong. And here you are. You're the nicest person I know. I am the meanest. You have dementia. My life is perfect. Explain that to me!
Mina's Mother: Sometimes the devil allows people to live a life free of trouble because he doesn't want them turning to God. Their sin is like a jail cell, except it is all nice and comfy and there doesn't seem to be any reason to leave. The door's wide open. Till one day, time runs out, and the cell door slams shut, and suddenly it's too late.
Here's the movie trailer. Hope you can watch the film.
