Agreed.
Wimber was a great student of and teacher of Scripture.
He didn't like folks adding to Scripture. He liked to read it and do it and to teach others to do the same.
Then, he expected God to confirm with signs following. HE did!
And does.
So, are you saying that faith doesn't play a part in this at all? That is what christianity is all about...faith. I don't expect God to perform for me to know He is real. He's not a carnival show. Signs are for those who have weak faith.
