The spiritual needs of the Muslim world, long neglected by Christian missionaries, came to the world's attention again when Samuel Zwemer dedicated himself to the advancement of the gospel in Arabia. It was a tremendous task, but a pledge the young American kept despite opposition, difficulty, and death. Zwemer founded the Arabian Mission in Bahrain to serve Muslims through medical care, Christian literture, and preaching. With a heart on fire for Muslim people, he relentlessly shared his vision worldwide, calling many to action. Zwemer's legacy of opening a long-closed door challenges and inspires us today to love and respect Muslims and to proclaim Jesus' name in the homeland of Islam.
