I preached yesterday at Feltham Evangelical Church (see here) about the need for us to have the Word faithfully and accurately brought to us. I particularity mentioned about my concern regarding what people imbibe outside of church whether it be online, in books or whatever means.
I specifically did not mention yesterday names of those to be kept away from. However, I take the liberty today to refer you to this list. I do not know all these people and I would not dismiss all of them in totality. Bill Hybels and Rick Warren, for example I suggest can be the means of benefit through their teaching if it is carefully consumed.
Nevertheless I feel that the list gives indication of those to be kept away from.
