This document discusses whether sincerity alone is enough for salvation. It argues that while Jesus calls for sincerity, sincerity is not the only requirement, as one can be sincere yet still wrong. Several examples are given of sincere people in the Bible who were not saved, such as devout Jews and Saul of Tarsus. The conclusion is that sincere obedience is what is required, not just sincerity, as evidenced by a quote from Romans 6:17-18.
