Yes indeedy. If you are fortunate enough to be approved you can report (as in be allowed to report) 15-minute increments. I knew that older ones, for example, were encouraged to report even the smallest amount of service and the cong. would include it in the report. But being approved to do so? So the ministry, this great and wonderful work Jehovah has set as a requirement for life (evidently/apparently) can be done/reported in 15 minute blocks, but one must be approved for such a privelege!!
1 When the end of each month arrives and all are asked to submit their field service report, what is your "cause for exultation"? (Gal. 6:4) Whether we are special pioneers reporting 130 hours in the ministry or publishers approved to report in 15-minute increments, all of us should rejoice in our whole-souled service to Jehovah.-Ps. 100:2.
And why was this instituted in the first place. Simply because reporting service is the equivalent to being one of Jehovah's Witnesses. When older ones or invalid persons were not able to achieve at least and hour of service in a month they became irregular or after six months inactive. And imagine how these poor souls felt when they knew this was the equivalent to no longer being a reporting publisher/jw. AND we come full circle. What is the true reason or purpose of the field ministry?
And, as a side note. Can you even Imagine putting in 130 hours.
