Ravi Zacharias' cancer has spread and he has been told by doctors that there is nothing more they can do medically for him.

The Christian apologist was diagnosed with a rare form of bone cancer in March 2020, and he has undergone rounds of chemotherapy. However, the condition of the area where the cancer metastasized has deteriorated.

Sarah Davis, daughter of Ravi and CEO of Zacharias International Ministries broke the news to the ministry's staff on Friday. She told them, "We have just learned that while the tumor in my dad's sacrum has been responding to the chemotherapy, the area where the cancer metastasized has actually worsened."

She added, "His oncologist informed us that this cancer is very rare in its aggression and that no options for further treatment remain. Medically speaking, they have done all they are able."

Zacharias' family will now be returning home to Atlanta, Davis has said, so that "our family can be together for whatever time the Lord gives us."

The apologist publicly revealed that he had been diagnosed with bone cancer in March through his Facebook page. He told followers that doctors had discovered a tumor on the sacrum, which was identified as a type of cancer called sarcoma.

Making that announcement in March, Zacharias said, "We are trusting the Lord in this, and we believe we have already seen evidence of His hand. We received literally thousands of messages from people all over the world saying you were praying."

He added, "I have every belief God directed and prompted my surgeon to his discovery of this tumor.

"Margie and I and our family are so grateful for your continued prayers for the journey that lies ahead. We are trusting the Lord for His purpose. Please do also pray that God will take away this horrific night pain, which is the most difficult part of waiting."

Zacharias recently shared a picture of himself and his wife on his Instagram page as they celebrated their 48th wedding anniversary. With the picture he wrote, "In sickness and in health."

He also added, "Our 48th wedding anniversary looked different than the others, but three things remain the same: our love for each other, the gift of family and friends who shower us with kindness, and the abiding faithfulness of our great God."

The post concluded, "Thanks to everyone who sent greetings and words of encouragement to Margie and me on this occasion.

"Please keep us in your prayers as I battle cancer, and accept our heartfelt gratitude for your love and friendship."
