Evangelist Franklin Graham once revealed that his father, world-renowned North Carolina preacher Billy Graham, had one Bible verse displayed in large letters all around his house, and he called it his "life verse."

He once explained that his father Billy Graham had "a Bible verse pinned up on the wall in his bedroom, printed in VERY large letters."

He said it was pinned up "in the dining room, his bathroom, and several other spots around the house!"

"Back before his 95th birthday, he was working on a sermon based on this key Scripture. It was his passion to memorize it, to saturate his heart and mind with it. He made it his life verse," Graham said.

He revealed that the verse was Galatians 6:14, which reads: "But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world."

Graham called it "a great verse for us to live by."

A January 2013 post on the Billy Graham Library website noted that the evangelist identified John 3:16 as his favorite Bible verse back in 1995, which reads: "For God so loved the world that He gave his only begotten Son that whosoever believeth in Him should not perish but have everlasting life."

Billy Graham said at the time that it's the one verse he always preaches on his evangelistic crusades.

"It has only 25 words in the English translation of it, but it is the Gospel in a nutshell. Someone has called it a miniature Bible," he said.

He also urged Christians to make an effort to understand the Bible, which he said is more important than any other book.

When offering advice on how to begin exploring the Bible, he said in 2016 that first-time readers can start with the Gospel of John.

"I suggest you begin with the Bible's center or focal point, which is Jesus Christ. All the Old Testament points forward to Him, and all the New Testament tells us about Him. He came down from Heaven to forgive us and make us part of his family forever — and through the Bible we discover this great truth," Graham wrote, adding a reference to John 20:31 that states the Holy Book was "written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name."
