Franklin Graham recently revealed that his legendary Christian Evangelist father Billy Graham once questioned whether or not if the scriptures were completely the commanding word of God.

"Sixty-five years ago this August was a pivotal time in my father's life. In fact, my son Will Graham recently traveled to San Bernardino, California, to help commemorate, on behalf of my father and me, a decisive step of faith that occurred at Forest Home Conference Center that summer of 1949. My father was 30 years old and preaching around the country. Another young preacher he knew had been questioning whether the Bible was truly and entirely the authoritative Word of God," wrote Franklin Graham in a letter on the Billy Graham Evangelistic Association (aka BGEA) website.

Franklin also revealed how his father's previous doubt affected him mentally, physically and spiritually nearly 70 years ago.

"The issues this preacher raised began to trouble my father. Although he never doubted the truth of the Gospel, he wrestled over whether he could fully believe everything the Bible teaches. He even started wondering if his questions might cause him to give up preaching. He took his struggle with him when he traveled to California, where he was scheduled to speak at Forest Home in August and then begin a citywide tent Crusade in Los Angeles a few weeks later," wrote Graham.

He mentioned how God freed his father from his former doubt that eventful night in 1949, before he became the world renowned television evangelist.

"Late one night at Forest Home, discouraged and unable to sleep because of the burden that filled his mind, he got up and went out into the moonlight for a walk. In the nearby woods he came upon a tree stump, and he opened his Bible and laid it on the stump. Then he poured out the agony of his heart to God. He knew the matter had to be resolved one way or the other. Finally he knelt in the shadows by the stump with the Bible open before him and prayed, 'Father, I am going to accept this as Thy Word-by faith! I will believe this to be Your inspired Word.' At that moment, he later said, he felt the burden lift and sensed the freedom and power of the Holy Spirit in and around him," wrote Graham.

Billy Graham's outspoken son also gave some words of inspiration to Christians who had similar doubts like his father did many decades ago.

"This same struggle stirs within many people today. There are voices across our land that emphasize parts of the word of God while minimizing scriptures that make them uncomfortable. As I contemplate the havoc this creates within the church, I am reminded of an old Bible teacher, now in heaven, who once told me that the best way to interpret Scripture is with other passages of Scripture. The Bible is true from cover to cover. 'This Book ... shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success (Joshua 1:8, NKJV),'" wrote Graham.

"There are people you know and people all over America who do not yet understand that the only way to heaven is through repentance and faith in Jesus Christ. They need to hear this message, and we ask for your help to make that happen. Be sure your pastor and others in your church know about My Hope 2014 with Billy Graham," he concludes.
