The residents of Salsbury received a tremendous amount of assistance after the tornadoes ripped through their community a month and a half ago. They were grateful for the assistance, as would anyone who finds themselves with nothing left. A restaurant donated leftover food. It would have normally been thrown out. Piles of clothing, much of it dirty was donated by the garbage bag full.
Disposable income is used to make financial contributions.
That is not the example in the story of the Good Samaritan. The Samaritan uses his own oil and wine to dress the wounds. He took his time to care for the injured man. The Bible doesn't say, but I wonder if he gave the man any of the clothes he was traveling with certainly not something that hadn't been worn for years laying in the back of the closet. That is the nature of mercy.
