Deep religious mysteries, which had baffled human minds for centuries, had been unraveled. The second advent of Christ, the tribulation of the Anti-Christ, the prevalence of Gog and Magog, the coming of the Mahdi and similar other topics were mysteries which affected the two great religions of the world, Christianity and Islam, both contending for the mastery of the world, and an inspired man was indeed needed to lift the veil from the face of these mysteries.

Such a man was Hazrat Mirza Ghulam Ahmad. He was gifted not only with inspiration to elucidate the deepest mysteries, but also with the faith and energy, which enabled him to give a new direction to the dissemination of Islam, which had hitherto found the West deaf to its message. Christianity was out to conquer the Muslim world; in temporal matters it had ousted Islam, but in the spiritual domain, Hazrat Mirza Ghulam Ahmad made a bold start and gave a challenge to Christianity in its very home. It is as a result of that challenge that mosques are being built in the great centres of Christianity, that a vital change is being brought about in the attitude of Europe towards Islam, and that thousands of cultured and advanced Europeans are finding a haven of peace under its banner.
