This is offensive (or perhaps ludicrous) to a great many people, who would have us doubt the words of holy Scripture and change what they say according to the fashion of the times. Nevertheless, it remains absolutely true, whether or not our freedom to believe and follow it is protected by constitution or law.
For our Lord and Savior Jesus Christ is our only teacher; concerning him this weighty command was given from heaven to all human beings, “Hunc audite” (“Listent to him”) [Matt. 17:5]. He was not a mere human being or angel. He was not only truthful, wise, and powerful. He is the eternal truth and Wisdom itself, and almighty God. He knows very well what to say and how to say it, and he can accomplish through his power everything that he has said and promises, and can make it happen, as he says, “Heaven and earth will pass away, but my words will not pass away” [Luke 21:33], and, “All authority in heaven and on earth has been given to me” [Matt. 28:18].

Some might call them “dangerous extremists” who believe something with such absolute conviction. Yet if God has indeed spoken, how can we deny the things that He has said? Would that not be the height of folly?
We can just as easily reverse the charge and say that those who reject the authority of God’s Word are “dangerous moderates” or “foolish skeptics,” who would incite the wrath of our Creator upon us all.
Christians are not distinguished from Muslims (or anyone else) by the presence or lack of sincere doctrinal zeal. The true distinction lies in the doctrine itself. Christianity is based upon a man who proved His teaching by rising bodily from death and ascending to heaven. His resurrection is a well-attested matter of historical fact. The doctrines of contrary religions have no such foundation in truth. Therefore, where God’s Word speaks, Christians listen.
