There is some fear that I'll be bringing coals to New Castle--but I think the series will be informative and fun.
I think I have already mentioned that when I first became a Christian I was a strong Arminian and a strong per-trib pre-mill dispensationalist. Two books radically changed my theology, because I found each presented interpretations much more aligned with scripture: Sproul's Chosen By God and Philip Mauro's The Gospel of the Kingdom (1928).
What is an interesting aside to these two books is that they belie the notion that civility has gone the way of the dodo. Sproul's book, the more modern by far, is gracious in its attack on Armininianism. Mauro's book in its attack on dispensationalism--not so much.
