There is a great difference between knowledge and belief. How do you know that you are following Jesus. You may believe it, but that is not knowledge. If you say that you follow the Bible, remember that all the major first and second millennium heresies can be defended from the Bible, including the Gnosticism that many so-called Christians indulge heavily in.
Which teachings of Christ do you not follow? The Sacrifice of the Eucharist is one, I believe. Confession and repentence? Salvation based in part on deeds (Matthew 25)?
Most of the people who proclaim that it is all about Jesus really believe that it is all about Paul, or Isaiah, or the dude that looks back at them in the mirror because that dude cherry picks his own selection of Scripture and then interprets it on his own. Most of the ones that I have come into contact with or read about, anyway.
