Garden of Eden was a setup...

[ChristIsLord]

So, ChristIsLord. Is every passage in the Bible supposed to be taken literally, or are there metaphors and analogies that are simply symbolic to make a point?

Jesus spoke in parables; the four Gospels are loaded with them and Jesus explains why he used them. I challenge you to investigate this one for yourself.

God used parallels through the Old Testament, foreshadowing the coming of Christ. Here are two examples that come to mind.
Consider the story of Joseph in Genesis where God used Joseph to save the 70 Jews of his family foretelling of how He will use Jesus to save the Jews and Gentiles.
Another example I like and Jesus refers to this is the story of Jonah where Jesus tells the disciples of how he will spend three days in the tomb just like Jonah spent three days in the belly of the whale.

"A mighty fortress is our God." which I want to say is something David said, is an example of a metaphor used in the Old Testament.

I would not go so far as to label certain passages in the Bible metaphors that I either do not understand or cannot come to accept as literal. but there in there.
