There is no “If … then” with God.  There is nothing you need do nor promise in order to get what you need.  You need not bargain with your Maker.  Do you not realize that you are one with God?  You are the One Eternal Mind expressing Itself in this particular lifetime as a mind with a given name.  There is no need to bargain with your Self.  The only need is to realize who you are and how Mind works.  IF you reach this beautiful point of realization, THEN you will co-create what you need.  IF you act and think as the God-being that you are, THEN you will begin to see miracles in your life.
