I know of a church making a difference in their own backyard. Each Saturday they give out cooked meal and clothes to the needy in their community. They set out tables of clothing next to the church building. They also have inspiring literature for anyone interested in having a relationship with the Lord.
Our church has a Community Service program all year long. We collect food for the needy. And many people receive clothing and other home necessities as well. But we also try to be alert to any of our members in the congregation when they are having a time of need and try to help in any way possible. We need to care for those abroad, but we should not forget those around us.
Missionary work is great and we support our missionaries financially too.
