Most if not the majority of churches do have outreaches for non-members. I just believe in doing what you can where you at. The needs of a community are different and I think there is enough "need" out there for churches to find something to get involved in.
As stated earlier, it doesn't have to be on a grand scale - if you notice the kids in your neighborhood or church are lacking in shows and clothes, even something as small as a clothing drive can make a difference. Small steps do eventually add up.
and good points Rudey.
