What is the meaning of Allah's saying: "But it was made to appear to them as such" [Qur'an 4:157], and what is the divine wisdom behind this resemblance?

The Jews lied in their claim of killing Jesus, peace be upon him, mentioning him by the message mockingly, just as they lied that they crucified him. Rather, it was made to appear so to them, for Allah raised him to Himself after casting his likeness upon another person, and that person was killed in his stead. The Jews and Christians differed concerning his killing, so they denied the truth and followed conjecture. As for Jesus, peace be upon him, he will descend before the Hour to rule by the law of Islam, break the cross, kill the swine, and abolish the jizya.
