I'm currently watching a lecture series called "The History of Christian Theology".  One of my favorite parts of the series happened in yesterday's lecture when the subject turned to typology (a way Christians read Scripture).  Typology is looking for pre-figurations of Jesus (example: Jesus as the temple) or of other things (example: Israel being a pre-figuration of the church).
Here are some of my favorite typologies:
Jesus as the Passover Lamb
Jesus as the Temple
Jesus as the Rock from which water sprung to quench the thirst of the Israelites
wood of the ark as the wood of the cross.
What is your favorite typology?
