That is what the Spirit is for...to lead us in ALL TRUTH. If I understand the statement and why it was said, it is because all the church teaches is "say the name Jesus" and be saved. To most in the church He is nothing more than a trinket, or a native American dream catcher. He is not a shining example of how to live. To the church He died to wipe away the Law...not just sin, but the ability to even call a sin a sin. For most that I have encountered, their belief seems to be the same belief that the demons have. They believe He was/is real, He died and rose from the dead. But they do not believe what He said, which was over and over again "OBEY".
