"My sisters, if you would bring your manner of dressing into conformity with the rules given in the Bible, you would have an abundance with which to help your poorer sisters. You would have not only means, but time. Often this is most needed. There are many whom you might help with your suggestions, your tact and skill. Show them how to dress simply and yet tastefully. Many a woman remains away from the house of God because her shabby, ill-fitting garments are in such striking contrast to the dress of others. Many a sensitive spirit cherishes a sense of bitter humiliation and injustice because of this contrast. And because of it many are led to doubt the reality of religion and to harden their hearts against the gospel. MH 207.3"
"In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;"
EGW directly connects the idea of modest apparel with helping the poor, which aligns with the principle of 1 Timothy 2:9 regarding modest dress.
"Christ bids us, “Gather up the fragments that remain, that nothing be lost.” While thousands are every day perishing from famine, bloodshed, fire, and plague, it becomes every lover of his kind to see that nothing is wasted, that nothing is needlessly expended, whereby he might benefit a human being. MH 207.4"
"When they were filled, he said unto his disciples, Gather up the fragments that remain, that nothing be lost."
EGW directly quotes John 6:12. The context is also similar, emphasizing avoiding waste and using resources wisely.
