On the door of the mosque in Damascus, which was once a Christian church—but for twelve centuries has ranked among the holiest of the Mohammedan sanctuaries—are inscribed these words: “Thy kingdom, O Christ! is an everlasting kingdom, and thy dominion endureth throughout all generations.” Though the name of Christ has been regularly blasphemed, and the disciples of Christ regularly cursed, for twelve hundred years the inscription within it has remained unimpaired by time, and undisturbed by man.
The inscription was not discovered during the long reign of Mohammedan intolerance and oppression; but when religious liberty was partially restored, and the missionaries were enabled to establish a Christian church in that city, it was brought to light.
