They are teaching narratives.. Jesus was a Jew.. he learned the stories of redemption.
Islam can never explain away the truths found in the N.T., from its claim that Jesus was not deity, the Son of God, to Islam claiming that God/Allah lied and someone other than Jesus really died on the cross by chaning the face of the subtitute to appear as Jesus.......to claiming that the O.T. and the N.T. are not valid because its a TRANSLATION of the original text (which I find

amusing because here on this site are some that are using langaues that are translated from their tongue into English (which begs to ask......since this communication from their original tongue has been translated........they are always speaking in deciet, according to the logic presented by ISLAM, so its futile to translate your tongue into another as communication is impossible)......

and worse yet.......when they attempt to teach Islam in English.......their own teachings are CORRUPTED, according to their logic......every American that has ever been converted (who can't read in the original text of the Koran)....have been corrupted and taught decietful acts.
While in the real world........the world of academia has in its possessiono over 5500 full, partial, and pieces of original manuscriptes/epistels form the 1st and early 2nd century all written in orginal Greek..when compared to modern translations......nothing is lost because Greek was the Universal Language of the 1st century.
Islam rejects this truth......and claims that Allah inspried an illerate sheep herder and trader/thief......to write MORE faith 600 years , after The Faith was ONCE delievered to the saints of the 1st century (Jude 3)
Speaking of parables......teachings by Axiom. There is one that goes something like having one's cake and eating it also...........
Parables are parables and are identified as such by the content, context and subjectmatter. Law is Law, The words/teachings, to include the lessons taught by parable are truths presented by Jesus and are law to be used as judgment (John 12:48)..........just as are all the books of the Holy Bible which are all inspired by the God of Creation and will be used in judgement when those books from God are compared to a person's opened Book of Life (2 Tim. 3:16, Rev. 20:12)
Example of a "story"....i.e., parable/allegory. The entire Book of Revelation is stated to be "signified"...i.e, symbolic text (Revelation 1) Jesus parable about Hades/Paradise and the Rich Man taken to Hades (realm of the dead)there after death (Luke 16) The text qualifies itself as a teaching parable "There was a rich man.........." It begins as does all such "STORIES".
But even the stories are words of wisdom spoken by the Christ and used as tools of judgment.......
Another parable. Luke 11.......all parables are identified by content, context and subject matter..........they are calling TEACHINGS (Luke 11:1........Lord teach US........"
