Ahh, but we are, we are. Warren does not preach the Jesus of scripture. Believers don't accomplish anything - it is the Holy Spirit who does the work. Yes, He can draw people to Him even though the words of false prophets point to man. It is His work, not ours. We are just instruments to exalt His name and not that of man's works. But I know you won't agree with that either. However, I will leave you alone before you continue to name call and other things.
I Cor.3:1 And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. 2 I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able. 3 For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
Rom 16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
Consider yourself marked.
