Christianity versus Islam!
(St Francis challenges the Sultan of Egypt)

St. Francis of Assisi lived during the time-period that the Holy-Land was embroiled in the Crusades. In his zeal to convert the Muslims or die as a martyr for Christ he traveled to the Holy Land. Risking a cruel death He and his companion crossed the Crusaders line during a siege at Damietta Egypt and marched into the Muslim camp.
By God's they were brought to the Muslim leader; Sultan Malik-al-Kamil (nephew of Saladin).
To the Sultan St. Francis made the following spiritual, fire-challenge to Islam:

I found what you were looking for in St. Bonaventure's Major Legend Chapter 9:8:
      For the Sultan, perceiving in the man of God a fervor of spirit and a courage that had to be admired, willingly listened to him and invited him to stay longer with him. Inspired from heaven, Christ's servant said: "If you wish to be converted to Christ along with your people, I will most gladly stay with you for love of him. But if you hesitate to abandon the law of Mohammed for the faith of Christ, then command that an enormous fire be lit and I will walk into the fire along with your priests so that you will recognize which faith deserves to be held as holier and more certain." "I do not believe," the Sultan replied, "that any of my priests would be willing to expose himself to the fire to defend his faith or to undergo any kind of torment." For he had seen immediately one of his priests, a man full of authority and years, slipping away from his view when he heard Francis' words.
"If you wish to promise me that if I come out of the fire unharmed," the saint said to the Sultan, "you and your people will come over to the worship of Christ, then I will enter the fire alone. And if I shall be burned, you must attribute it to my sins. But if God's power protects me, you will acknowledge Christ the power and wisdom of God as the true God and the Savior of all." The Sultan replied that he did not dare to accept this choice because he feared a revolt among his people. Nevertheless he offered him many precious gifts, which the man of God, greedy not for worldly possessions but the salvation of souls, spurned as if they were dirt. Seeing that the holy man so completely despised worldly possessions, the Sultan was overflowing with admiration, and developed an even greater respect for him. Although he refused, or perhaps did not dare, to come over to the Christian faith, he nevertheless devoutly asked Christ's servant to accept the gifts and give them to the Christian poor or to churches for his salvation. But, because he was accustomed to flee the burden of money and did not see a root of true piety in the Sultan's soul, Francis would in no way accept them.

My addition: Note: St. Francis was not 100% certain whether God was the one inspiring him to make his challenge, or whether it came from his zeal (since he was desiring martyrdom).For that reason Francis said to the Sultan, "If I burn may it be attributed for my sins". (A man who is walking by faith has a good idea, but is not always certain, that God is the one who is inspiring all of his actions)

Referring to our re-making of Francis's spiritual Fire-Challenge, unlike the saint  I am 100% certain that God is the One who is inspiring it. If you read my essay in its entirety , and all associated links, I will prove my claim.   email:
The Sultan refusal  was hundreds of years before the advent of the mass-media. Back then the Sultan could easily back down, since only those in the room would know. For that reason, his refusal to stand up to the plate didn't raise any eyebrows.  If such a challenge was made today, covered by the cable news network, the Muslim leaders couldn't back down as it would be fatal to the standing of Islam in the eyes of its billion plus followers! {as the eyes of the entire world will now be watching in anticipation}

On another note, if the Sultan would have stood up to the plate Francis would have prevailed because the Christian religion of the 12th century was a far holier religion (the12th century was hundreds of years before the Reformation. In those days, Christianity pretty much meant one interpretation - Catholicism)
    Nowadays, hundreds of years since the Reformation, there exists so many different variations of Christianity. Most, if not all have watered-down the faith to varying degrees.  In my opinion some of the watered-down versions, the ones that don't require good works, aren't necessarily any holier than is
