There's a difference between a community helping and an organization helping. While organizations can help many, my heart is with the small, local community. It's friends, neighbours and family actually caring for those whom they know. They know because they care about them. I give my time, skills, and money to these people.
Here's a recent example. I was helping my brother (Christian brother) build a porch on his house. One day when I arrived I saw that his large family and grown considerably by the addition of 3-4 more kids. I didn't ask but later in the day he explained that another family we knew was going through a hard time. In short the husband was in jail and the wife and mother of 8 kids was on her own with the kids. Adding to the crisis was the fact that their landlord wanted her out of their rental house in two weeks and the husband was in no position to provide financial support. My brother had opened his home to care for the older kids for however long it was needed.
While none of us condoned the husband's behaviour, the wife and children were still in a very difficult state. Many gave anonymously of food, money, etc. Others helped find her a new home to rent. Still others painted the walls and cleaned the house. We're not special. Nobody knows our names or what we did. There was simply a family in need so we did what needed to be done because that's how humans should be. We're not unique; we just try to care. Similar events play out everyday around the world and the world never hears about them.
I don't know if this is what you had in mind but I do know that if more of us would get involved personally and look closer to home for our largess and care then the large organizations could focus on disaster relief where the need has overwhelmed even the local community.
