Why would someone conclude that it's needful, even crucial, to put everything else aside and devote two weeks (perhaps one's only vacation time all year) to a course of spiritual study? This endeavor may well demand significant sacrifice, prayer, and reordering of priorities. What would prompt this step?
For the student of Christian Science who is considering Primary class instruction (provided for in the Manual of The Mother Church by our Leader, Mary Baker Eddy), understanding why we should have class instruction is as important as feeling that we may want to do it. What is the right motive? If it's to make our lives more comfortable, to gain some kind of "status" or approval from others, or to provide companionship because we feel lonely, it isn't yet time to apply. These motives are basically self-serving.
What about taking class instruction in order to decide whether Christian Science really is the truth, and whether it heals? Actually, a student should already have consistently relied on Christian Science and experienced its healing power before coming to class. Is it legitimate to take class in order to be freed of some physical ailment? Mrs. Eddy cautioned against the motive of taking class instruction for the purpose of being healed.
