Trinity Broadcasting Network, the world's largest religious television network, has released US evangelist Billy Graham's last recorded message to mark four years since his passing. 

Titled "Are you ready to die", the video features Billy Graham preaching, as well as footage of him sharing the gospel at his crusades. 

Graham died from natural causes in 2018, at the age of 99 in North Carolina. He had retired from ministry in 2005. 

His son, Franklin Graham, also featured in the video and can be heard saying: "Four years ago this Monday, my father went home to Heaven. Before he died, his heart burned with the desire to share the Gospel one last time."

He continued: "In many ways, it's hard to believe that my father has been gone four years. We all miss him greatly, but I know that I'll see him again someday in heaven." 

Billy Graham reached more than 200 million people through his appearances and millions more through his pioneering use of television and radio.

During his last sermon he said he wanted to leave people with the "true message" and shared how he had been brought to tears many times after travelling from city to city and witnessing how far people have wondered from God. 

"People don't want to hear that they're sinners-to too many people it's an offense. The cross is offensive because it directly confronts the evils which dominate so much of this world."

He concluded: "Of all the things that I have seen and heard, there's only one message that can change people's lives and hearts

"I want to tell people the meaning of the cross. Not the cross that hangs on the wall or around someone's neck. 

"But the real cross of Christ that's scarred and bloodstained."
