Next month, legendary evangelist Billy Graham will release his highly-anticipated new book, titled Where I Am: Heaven, Eternity, and Our Life Beyond, his son Franklin Graham has revealed.

In a statement released on Facebook, Franklin Graham, a popular social commenter and the president of the Billy Graham Evangelistic Association, shared some details about the upcoming book.

"It was great to be able to visit my father this weekend at his home," Graham writes. "He has a new book coming out the end of September that he started working on before his 95th birthday."

The message continues: "He said, 'When I die, tell others that I've gone to my Lord and Savior Jesus Christ - that's where I am.' Jesus Himself said, 'Let not your heart be troubled; you believe in God, believe also in Me. ... I go to prepare a place for you. ... I will come again and receive you to Myself; that where I am, there you may be also' (John 14:1-3)."

According to Amazon.com, the new book will be "the Final Chapter" from Billy Graham in which the evangelist will share his thoughts on the past, the present, and the reality of eternity.

"Although Billy Graham may no longer preach from the stadiums of the world, in this book you will sense his heart still beats strong with the resounding assurance that he will spend eternity with Jesus Christ, the Savior of the world. In Where I Am, Mr. Graham invites and strongly encourages all of us to contemplate our eternal hope," the preview reads.

In the book, Graham, now 96, will provide insight into the Bible's message in all of its 66 books, focusing on messages of truth, warning, love, and the certainty of the future.

Where I Am: Heaven, Eternity, and Our Life Beyond, which comes out on Sept. 29, is the 33rd book released by the beloved pastor. His last book, The Reason for My Hope, came out in 2013 and is credited with sparking over hundreds of decisions for Christ.

Last year, the Billy Graham Association released a film titled "Heaven" which featured a never-before-seen message from Billy Graham.

The project was filmed in 2013 and it shows Billy Graham discussing his imminent death.

"I know I'm going to Heaven. I'm looking forward to it with great anticipation," said Graham in the film before explaining how others can also have that peace by asking Jesus Christ to be their Lord and Savior.
