Or smart enough. Or whatever enough. And everyone needs to come up with their own, personal, spiritual response to the great unknown of death. It's something we've all got to do. Death is a truly universal human experience.

One of the absolutely essential tasks of religious education, is to insist on people taking personal responsibility for understanding and interpreting the Bible. You should not take my word, or anyone else's word, as final, on any passage of Scripture you hear or read. People have to learn to listen for themselves to the Holy Spirit speaking within the written words on the page. It is too important to leave to anyone else. And it is too dangerous, to sign off that responsibility to another person.
