It is a good thing to be earnest and sincere. Having these traits, however, doesn’t mean we are right or wise in regard to our desire. We can be sincerely wrong or misinformed. One of the common beliefs of today is that all religions are basically the same and as long as one is sincere then it will be ok. In this passage in Mark 7, however, Jesus confronts the failure of religion and reveals that even the best and most sincere efforts to reach God are fraught with failure. Jesus challenges his audience to rethink how one can approach God.
