2011 preaching results:
Hours preached: 1.7B
New Baptized: 263K
If we do the math, it took about 6,464 hours of preaching to have 1 person baptized in 2011. An average publisher preaches about 10 hours per month, therefore, it takes 1 publisher almost 54 years of preaching to convert 1 person into a jw. This is without subtracting the jw's kids that may almost be half of the newly baptized.
Does the WT still write that door to door preaching is the most efficient way to spread the good news?
