Have you ever said, "As long as...."? "As long as I can....." or "As long as this happens" or "As long as he doesn't..." or "as long as it..." Think about your "as long as..." list. What is your foundation?  I'll tell you mine.  As long as this is true that's all I need to know.  As long as Jesus is God and as long as I believe him.  If you'd want more to be sure of or think more is needed, you don't know all that comes with that.
