The Journey in San Jose shuts down church 2-3 times per year and takes everyone out into the community to tackle 15 or so specific community projects. Things like home make overs for families in need, teacher care kits, roadside clean up, painting & landcaping at public schools, hosting a carnival at a children's shelter, etc.
Projects are always different because volunteers find the need and then lead them with a team.
Number of visitors [especially those who are not Christians] actually increases on these Community Impact Days - everyone sees the value in helping right in our neighborhood.
10% of The Journey's budget goes toward these days and other specific community needs.
might be well worth a try!
