Students will celebrate 'Bring Your Bible to School Day' October 6.

Focus on Family estimates that over 100,000 students participated in Bring Your Bible to School Day in 2015. Children around the country posed with their Bibles on Twitter, Facebook, and Instagram. An estimated 300,000 students will participate in the event on Thursday.

Schools may not impose or promote religion according to the American Civil Liberties Union, but students are allowed to engage in religious activities that they start. Those activities cannot "cause a disruption or interfere with the education of other students."

"Students don't lose their religious freedoms when they arrive at school in the morning," said Jim Daly, President of Focus on the Family. "The First Amendment recognizes the rights of students to talk about their faith in school and read their Bible outside of Classroom time. 'Bring Your Bible to School Day' encourages children and teens to understand their religious freedoms and to be a voice of hope and bring their whole selves to the classroom."
