Leilani Haywood with Adrienne S. Gaines

Healing ministry pioneer Frances Hunter died early Tuesday morning after battling kidney failure and congestive heart failure for more than two years. She was 93.

Hunter and her husband, Charles, spent nearly 40 years leading "healing explosions," where they prayed for the sick and taught Christians about the ministry of healing. Known as the Happy Hunters for their ready smiles and quick humor, the couple wrote more than 50 books about divine healing, including the best-seller How to Heal the Sick.
