The son of legendary Christian televangelist Billy Graham, Franklin, recently talked about the controversy that surrounded his previous speech after he received the 2014 Watchmen on the Wall Award on May 22.

"Heaven is not for cowards! Recent comments I made while speaking at an event in Washington, D.C., have drawn some controversy. In a challenge to those who are afraid to speak out on moral issues addressed in the Bible, I referenced a chilling passage-a warning from God about the most catastrophic indictment the world will face someday," wrote Graham on his father's official website, "But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone" (Revelation 21:7-8).

The 62-year-old minister also offered advice to other pastors regarding the issue of sin.

"Followers of Jesus Christ, and especially pastors and church leaders, have a responsibility to speak the truth of Scripture, calling sin what it is, and acknowledging that it has always reigned in the hearts of the human race. It is not any worse today than it was 'in the beginning.' After all, sin brought about the Great Fall and then the Great Flood because 'the wickedness of man was great in the earth' (Genesis 6:5). It is not just a debate about abortion or homosexuality; all sin is immorality-and all immorality is evil. In America today we are experiencing an epic drought. It is not just the basic misunderstanding of the Word of God; it is the absence of God's complete Word," wrote Graham.

Graham then encouraged all Christians to become "fearless ambassadors of Christ" like the Apostle Paul was after Christ's resurrection.

"Who does not remember the cowardice of Peter, the salty fisherman-the sea-walking but fainthearted follower-who denied Jesus Christ? Out of his anguish he overcame his greatest failure, and a bold and mighty faith emerged. He became a soul-winning fisher of men-the disciple who instructed others in serving as effective shepherds of God's flock (1 Peter 5:2). He wrote: 'If anyone speaks, let him speak as the oracles [the very Word] of God' (1 Peter 4:11). We must understand that the very Word of God is the Bible," said Graham.

"Let's overcome cowardice with courage. Let's be fearless ambassadors of Christ and stand strong for the glory of God our Savior, pulling others from the fire of eternal judgment (Jude 23)."
