Well, when I first came on here, I was COMPLETELY against christians drinking alcohol period. There was no need to talk to me about it, I had it made up in my mind I was right, and everyone else who opposed me was wrong. Now, in the "reformed and alcohol" thread, you can see I have changed my tune. I had come to find out that it wasn't a sin to drink, though I have no desire to drink, and wish others wouldn't due to the ill effects it can have in one's life, and I believe their witnessing, but I would never run anyone outta town who drank.
I used to have a mixed up view of the Trinity, where they were three, but Jesus was not God, neither was the Holy Ghost. I had God as God, Jesus as the Son of God, yet not God, and the Holy Ghost as the Holy Ghost, yet not God. It was over time, that I read a lot of posts where people discussed the biblical view of the Trinity, and then one day, by His grace, it "clicked", and I saw the Trinity in the correct view. I never debated my view, but I did read what others had to say about. So yes, BB has been IMMENSELY helpful to me.
