Anne Graham Lotz and her husband were married for 49 years. On her website, she referred to Danny Lotz as “God’s Gladiator.”

“Danny and Anne were married for forty-nine years. At the age of fifty Danny developed a severe case of Adult 1 diabetes. For over ten years following his retirement from dentistry he fought the ravages of the disease, earning him the beloved nickname, God’s Gladiator. He lost the sight in one eye and the hearing in one ear. His heart disease required five stents in his arteries. His renal failure dictated three days of dialysis each week, five hours each time. And yet he never complained, never slowed down, never gave up, never stopped investing in the lives of others. As a New Yorker he was plain spoken. As a German he was stubborn. As a Christian he was a compassionate servant leader. He was more than a man’s man. He was God’s man who triumphantly finished his race having fought the good fight, and having kept his faith firmly focused on the kingdom of God first,” the website reads.

“He moved to our Father’s House on August 19, 2015 and received the accolade of his Savior, Lord, and King who presented him with the Crown of Righteousness. We salute you, Danny Lotz. And we will never forget you.”

Anne Graham Lotz will no doubt rely on her strong Christian faith as she navigates her heartache. She will surely find peace in the prayers said by many in the coming days.
