"Dear Dr. Sala," writes a friend of Guidelines. "I do have one question that has been bothering me for a long time....  How do I know that I can claim a promise of Scripture when it is (in the context of the Bible) spoken to someone else?"  Our friend went on to quote Mark 11:24, where Jesus said, "Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours."
