Surely if you read the bible you're familiar with the verse 1 john 2:19.
"They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us."
i am indeed. its a key point from the baptist way of thinking, and it does not apply to me. i believed, and i was a christian. a real christian. as real as i could ever be of anything, i believed without question and it wasn't something i lost over night.
