"A test whereby we can know whether or not revelation is from God: 1. Is it contrary to instruction from a living Prophet? 2. Is there anything secret? 3. Does it bring harmony and peace of mind? 4. Does it square with the scriptures? 5. What have you done yourself to ask of the Lord? 6. Are you keeping the commandments? By answering this series of questions, you can know by the Spirit whether or not the information come from God."
