This can be the rule of thumb for those who serve and just can't stop blaming others by not following their examples and respond as if they can't find any other reason why this fellowship is failing.
If your only responses are "I already did my best", "Why can't others put more effort like me to serve?", then you are already on the wrong path.
It is rather that one responds: "Perhaps I should go study theology." And if one thinks theological study is for pastors and preachers, then this person is better off going to farming, because his diplomas or whatever degrees he has gotten, are garbage, he studied for the purpose of getting a good job, he studied for the purpose of good salary, for good positions and obviously, his offering is despicable for it comes from counterfeit talents. It is better that he refuses all church positions except those which require only the strength to sweep the floor, wipe the tables and clean the chairs.
I have seen enough of these people, these are like some of those whom I tutored, who only want answers but never the principles or methods of obtaining such answers.
The story of Mary's choice of the Word and Martha's choice of serving at that moment is a clear sign of the importance of theological study. Instead of just serving/caring.
