Right, he came to heal the sick, to set free those in prison, to open the eyes of the blind these are all allegorical of the new covenant. So a story says that the sick was healed and the blind eyes opened how shall be understand theses events? Literally or allegorical?
You see the bible used these allegorical terms to relate the kingdom of God. There is a literal portion to the meaning, but the image isn't alway what is meant to be taken literal.
Like for instance the feeding of the five thousand. The multitude in the wilderness having no bread.( Do you see the comparison?) The number of them was 5000 ( 5, 50, 500, 5000 are symbolic) They had no bread other than what God (Jesus) give them. (Also notice that Jesus told Peter to feed his sheep) He would also tell his disciples to feed them, they reply saying they had not enough money save for only 5 loaves of bread and 2 fish. (again symbolic) Jesus makes them to sit down by 50's in a group. And after all was full the disciples took up the fragments of 12 baskets (again symbolic) so that no piece would be left.(symbolic)
