Three well-known Christians are teaming up in an effort to flood Ravi Zacharias with well-wishes, prayers, and thank you notes as he faces a terminal cancer diagnosis.

Tim Tebow, pastor Louie Giglio, and Lecrae were able to spend time at the bedside of the beloved apologist on Monday.

"We just had the chance to see one of our good friends, Ravi Zacharias," Tebow says in an online video.

Zaharias' ministry announced last week that he has run out of medical treatment options for bone cancer. He had been in Texas receiving treatments since March, but returned home to Atlanta last week to spend his final days with family.

"Ravi's not doing very well," Tebow says. "So we are so grateful we had the chance to tell him 'thank you' for what he means to us."

The three men are encouraging others to also let Zacharias know what he means to them by using the hashtag #ThankYouRavi.

"It was such a great gift to all of us today, to be able to tell Ravi face-to-face and in-person the impact he's made on our lives. And we want to encourage you to do the same," Louie Giglio, the pastor of Passion City Church in Atlanta, says. "He would love to hear that from you while there's still time."

"It means a lot to him and it would definitely mean a lot to us. So, please, take the time. Thank you, Ravi," Lecrae says.

One of the special times of my life today seeing Ravi at his bedside and sharing what he has meant to me, and how much he’s inspired me. I would love for y’all to use the hashtag #ThankYouRavi to share what Ravi has meant to you - you can film your own video or post a comment here with the hashtag... thank you for helping encourage Ravi and his family in this time!
