step 3 does not read...." made a decision to do step 4" or " made a decision to do the rest of the steps". The Book says " being convinced we are at step 3..........convinced.......ie done steps 1 and 2 proberly and no we do not do step 1 the moment we walk in the rooms. First 43 pages all about step 1, the foundation step.
Anyway, the book continues........"just what do me mean and what do we do?"
Pages 60-64 tell us exactly what step 3 is all about and if we have done steps 1 and 2 correctlyy then step 3 is our plan for living,
Its all in the book and if your sponsor can not explain "exactly" what step 3 is about or says it is only a decision i would doubt his knowledge on the step, well meaning or not.
Step 3 is a decision but a decision to take action which e do not take is a decision not made.
