Professor Jeffrey Radisson

Professor Jeffery Radisson is an antagonist in the 2014 Christian drama film God's Not Dead where he was portrayed by Kevin Sorbo.

Radisson was born an only child; it is unknown what happened to his father or anyone else in his family besides his mother. Once a God-loving Christian, Radisson's life changed at the age of 12 when his mother was dying of cancer; despite his prayers, his mother died, leaving him alone. Ever since, he has hated God for taking everything from him, and repressed His existence by becoming an atheist. This time in his life is probably why Radisson began studying philosophy, and eventually became a philosophy professor.

At some point, Radisson fell in love with one of students, Mina Shelley, a few years before the events of the film. They were live-in boyfriend and girlfriend in the movie.

In 2014, Radisson forced his new students to write 'God is dead' with their signature on their paper. One student, Josh Wheaton, was a Christian and couldn't do it. Josh was now required by Radisson to speak from the podium during the last 20 minutes of the next three classes to prove the existence of God. Radisson had attempted to make Josh mess up, but during the last session, he had pressured Radisson into revealing why he hates God; he says that God took everything from him, revealing that he even knows the existence of God. The students now got to choose whether or not God was dead; beginning with Chinese student Martin Yip, everyone rose and said God was not dead. Radisson was defeated.

During this time, Radisson had been verbally abusing his girlfriend Mina for being a Christian, so she left him. That night after the third and final session, Radisson found the note left by his mother before she died, and he wanted to make amends with Mina, whom he deduced was at the Newsboys concert at Hastings Center. It began to rain and while crossing the street, a car hit Radisson and drove off. At that same time, two pastors, Reverend Dave and an out-of-town minister, who went to help Radisson. The out-of-town minister said Radisson's ribs had been crushed; his lungs are filling with blood and he will die soon. Dave says to Radisson that the car could've killed him instantly, but God gave him a second chance to believe in Jesus. Radisson redeems himself and announces he gives his life to the Lord before dying.
