Elijah! (But there are so many good ones). I get literally excited when I read about Elijah. Might be a little because of the song (Elijah Rock) but really it's about him standing up against Ahab (SO many funny Ahab moments) and Jezebel, and the fire show. Oh, and God appearing to him (not as a big scary fire or a tornado, but as a soft whisper —blows my mind.) God didn't appear to many.
Moses. Rahab! (she should be played by Angelina Jolie). Ruth is a big favorite for her faith; and Hannah (Samuel's mom). Definitely Samuel. Michaiah (saw the awesome vision and probably got hurt really bad; not mentioned much.) Mary Magdalene, as someone already mentioned. The Holy Mother. John, and of course Peter. (And whoever said, "Let us call down fire on this city and smite it" to Jesus, who wasn't too fond of that idea.)
Better to ask who I wasn't too fond of *cough*Solomon*cough*, or who we never really related to at all (Rachel... I'm Team Leah all the way, LOL).
