A verse that has been referred to a number of times during this conference is this one:
Now the serpent was more crafty than any of the wild animals the Lord God had made. He said to the woman, "Did God really say, 'You must not eat from any tree in the garden'?"
~ Genesis 3:1
The Genesis 3 attack has been used ever since. "Did God really say..." that children are a blessing and should be welcomed not killed? that marriage is between one man and one woman? etc.
I think, if the conference could be summed up in one sentence, it would be this: Yes, God really said it; the whole Bible, from beginning to end, is true.
