Bestselling author, theologian and pastor Tim Keller has said he has a reason to celebrate as he gave an update on his cancer journey.

On Friday, he said that this month marks two years since he was diagnosed with pancreatic cancer and he’s thankful that chemotherapy has been successful.

“I can call it a celebration with justification as the chemotherapies have reduced the stage 4 cancer that was found and God has seen it fit to give me more time,” he tweeted.

While he is he’s over one hurdle, he asked for prayer for another part of his journey.

“…we are also moving onto an immunotherapy trial at the National Cancer Center in Bethesda, MD as of June 1, 2022. This has shown great promise in potentially curing cancer, though it is a rigorous and demanding month-long program (that will need updates up to 6 months),” he tweeted.

The trial is an inpatient one, which means Keller and his wife, will be separated from one another.

“Your continued prayers for truly miraculous effects of the procedure and minimal side effects would be very much appreciated,” he added.
