The Apostle Paul didn't put on skits or have a 1st century version of a rock band, either. What was he thinking? Didn't he know he was too "heavy" and "boring" for the seekers?
The apostles did just fine.
The Gospel of Jesus Christ is the message of Christ Crucified for the remission of sin, unto ALL peoples.
There is no "Other Gospel."
Mr. Warren is not a preacher of the Gospel.
