Because He doesn't. He can't change your soul. He can speak with you, explain to you, but cannot make you learn or more importantly understand anything, as making you understand takes away your free will. Jesus had to physically suffer every pain so he could understand it.

As I understand the Crucifiction, Jesus already understood, but to experience it and to become one with his decision, as it were, he had to go through with it. He understood it, but. . . he could not make the lawful change of others without his death and resurrection.
