Fundraising for church building projects should probably be tackled from several angles. You need all the money you can get, and just having one push for fundraising f probably won't cover everything. Schedule a church fundraising event, so that you can take advantage both of ticket prices, and the supplementary fundraising ideas you can be doing at the event. Fundraising for church building projects takes ingenuity, so be creative when thinking up fundraising ideas for your event.
Fundraising for church building projects can also take the form of a letter, either to congregation members to ask for their help, or to businesses in the community who have shown their generosity to the church in the past. Businesses are particularly useful to ask because they know how much fundraising for church building efforts can help, as they know how much new buildings cost and everything that is involved. Explain in your letter exactly what your church building fundraising is about, and the purpose of the new building. People are more likely to give to projects they understand something about.
Fundraising for church building projects is a lot of work, but it can also be very rewarding. It's a great opportunity for the church to connect with the community that supports it, and fundraising for a church building can help keep the focus on just how much the church is growing everyday, and how important that growth is to the community.
