You might want to read the article before assuming it does that.
I respectfully suggest that YOU might want to read the article. All the way through, the writer quotes the Scriptures, and then the Koran, and clearly places them on an equal footing. He pronounces no distinction between them, whatsoever.
Toward the conclusion, he winds up the article by extensively quoting the Koran, and clearly giving it equal veracity with the Scriptures, by failing to state otherwise.
He never states whether he believes one over the other, or which is what. An unsaved individual could read that article and come away concluding that both books are valid, and that it doesn’t matter which you choose to follow; or even whether it matters if you reject them both and consider salvation from sin as optional or unimportant!
Acts 4:10 Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.
Acts 4:11 This is the stone which was set at nought of you builders, which is become the head of the corner.
Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
