Robertson will follow in the footsteps of her parents, Willie and Korie, who made a cameo in the original "God's Not Dead" film.
Other cameos include Hayley Orrantia ("The Goldbergs"), Ernie Hudson ("Ghostbusters"), model Robin Givens and singer Pat Boone.
Stars from the original "God's Not Dead" film Trisha LaFache, Benjamin Onyango, Paul Kwo and David A.R. White will be returning for the second installment. The Newsboys will also have a cameo."God's Not Dead 2: He's Surely Alive" takes place in the fictional town of Hope Springs, Arkansas, at a high school where teacher Grace Wesley, played by Hart, faces opposition when she tries to speak about Jesus openly in her classroom.
"With the principal and superintendent teaming up with a zealous civil liberties group represented by an attorney with no love lost for God, Grace faces an epic court case with the help of sympathetic and charismatic defense lawyer, that could cost her the career she had always dreamed of — and expel God from the classroom once and for all," reads a description of the film.
While the first "God's Not Dead" film dealt with an antagonistic atheist professor, the new film will address the freedom of religion, a topic that has become even more prevalent since last month's U.S. Supreme Court ruling that made state-level bans on same-sex marriage unconstitutional.
"God's Not Dead" is arguably one of the most successful faith-based movies of all time. The film cost just $2 million to make, and grossed over $60 million at the the box office.
Kevin Sorbo, who played an atheist professor in "God's Not Dead," the film's main antagonist, boasted about the film's success after it was released on DVD in September.
"'God's Not Dead,' dollar for dollar, has been the most successful movie this year by far and the most successful faith-based movie," said Sorbo.
The film also debuted at No.1 on the Nielsen Christian Videos Sales Chart, and No. 2 Nielsen VideoScan First Alert and Blu-ray Disc sales charts in August of 2014.
