"Importance of Economy Brother R has good business ability for some branches of the work, which would enable him to serve the office acceptably; but he has not educated and disciplined himself to be a thorough, efficient manager. Under his charge there have been grave neglects; a disorderly, disorganized state of things has existed, which should be promptly corrected. There are many little matters connected with his work that have not received attention, and as a consequence there are leaks. Losses and wastes are allowed that might be avoided. 5T 413"
"He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much."
The EGW passage directly discusses the importance of attending to details and avoiding waste, which is a practical application of the principle of faithfulness in small matters.
"up the fragments,” He says, “that nothing be lost.” It would have been better not to undertake so many large enterprises if by this means so many small matters must be left without attention, for the little things are like small screws that keep the machinery from falling to pieces. The word of God explains duty; it gives the rule of faithful service: “He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much.” 5T 413.3"
"When they were filled, he said unto his disciples, Gather up the fragments that remain, that nothing be lost."
The EGW passage directly quotes and applies the verse from John 6:12 about gathering fragments, making it a clear explicit allusion.
