Missionary Gracia (GRAY'-shuh) Burnham says her husband Martin's handcuffs rusted during their year-long captivity in the Philippine jungle, so that he could have escaped. But Burnham told C-B-N's "700 Club" that he chose to remain with her because she was too weak to flee from the Muslim rebels with him. While they weren't beaten or tortured, Gracia says she and Martin were denied physical intimacy. Once in a while, though, he would brush her hair. In their last conversation together, she says he talked about Psalm 100 and told her that even as hostages, they should serve the Lord with gladness. A short while later, Philippine troops sent to rescue them opened fire, Martin was killed and Gracia was wounded. Her newly published memoir is titled "In the Presence of My Enemies."
