I went from Roman Catholic to Word of Faith/Charismatic to about 3 years ago Reformed after encountering a former Dake/WOF follower on a Dake website who is now a Reformed pastor. He introduced me to Grudem, Piper, Berkhof etc. I read "Grace Unknown" by Sproul & highlighted & marked passages that I disagreed with & then went to the Word to prove MY point of view only to get hit by THE TRUTH & in turn convertd to the Reformed point of view. Romans 9 what the catch for me. I was in that chapter for weeks (months?) & finally had to admit I was WRONG. I believe I was already converted just not right in my doctrine. But then again maybe I wasn't. I then searched & found my current church "Church of The King McAllen" & have plugged in & am active. Finding "Desiring God" in a bookstore after it caught my eye "Hedonism!!!" was a major turning point as well.
Had the same problems as others here in that my so called "brothers & sisters in The Lord" started to dislike me when I started quoting MacArthur & Piper, Luther etc. Eventually found myself around a whole new group of believers.
Very uplifting reading others experiences here.
