Clarence Larkin

“A mystery is not something that cannot be known, but something that for the time being is hidden. I hand you a sealed letter. What it contains is a mystery to you. Break the seal and read the letter and it ceases to be a mystery. But you may not be able to read the letter, because it is written in a language with which you are not familiar. Learn the language and the mystery ceases. But perhaps the letter contains technical terms which you do not understand, learn their meaning and all will be plain. That is the way with the Mysteries of the Scriptures, learn to read them by the help of their author, the Holy Spirit, and they will no longer be mysteries.”

“FUTURE--Unfulfilled Prophecy. The "Requirements" of a Genuine Prediction are five in number: 1. It must have been made known PRIOR to its fulfillment. 2. It must be beyond all HUMAN FORESIGHT. 3. It must give DETAILS. 4. A SUFFICIENT TIME MUST ELAPSE BETWEEN ITS PUBLICATION AND FULFILMENT TO EXCLUDE THE PROPHET, OR ANY INTERESTED PARTY, FROM FULFILLING IT. 5. There must be a CLEAR AND EVIDENT FULFILMENT OF THE PROPHECY.”
