His parables are sometimes interpreted as allegories in the gospels themselves and in Christian tradition. In such an allegory, each element corresponds metaphorically to a class of people (e.g., false Christians), a heavenly reward, or some other topic. The gospel of John includes allegories but no parables.
Believed to be the words of Jesus, taught to him by the Father, Christians place high significance on the parables.
28 So Jesus said to them, "When you have lifted up the Son of Man, then you will know that I am he, and that I do nothing on my own authority, but speak just as the Father taught me. –John 8:28
