Hymn #443 in the 1875 Wesley Hymnal (or #431 in the Collected Works of John and Charles Wesley) is a remarkable call for faithful evangelism and intercession in the Muslim world:
1. Sun of unclouded righteousness,
With healing in Thy wings arise
A sad, benighted world to bless,
Which now in sin and error lies,
Wrapped in Egyptian night profound,
With chains of hellish darkness bound.
2. The smoke of the infernal cave,
Which half the Christian world o'erspread,
Disperse, Thou heavenly Light, and save
The souls by that impostor led,
That Arab-thief, as Satan bold,
Who quite destroyed Thy Asian fold.
3. O might the blood of sprinkling cry
For those who spurn the sprinkled blood!
Assert Thy glorious Deity,
Stretch out Thine arm, Thou triune God,
The Unitarian fiend expel,
And chase his doctrine back to Hell!
4. Come, Father, Son, and Holy Ghost,
Thou Three in One, and One in Three,
Resume Thine own for ages lost,
Finish the dire apostasy;
Thine universal claim maintain,
And Lord of the creation reign.
