You'll be feeling some flames yourself, for that, but I'm on your side. I wouldn't even donate if my own church caught fire. They don't speak out against the murder of the unborn, and they don't help people in the community who become homeless due to fire, people who have no insurance. I open my wallet for those people. Most folks I know who are in a position to help, do likewise. Never has our priest phoned to ask me to help a particular family, and he knows I could.
One of the life lessons I've had, which I particularly prize, is that individuals help individuals, and collectives help themselves.
That off my chest, I know nothing about this church in Wasilla and they may be exceptions to the general rule.
I was pointing out that any commercial building must carry insurance--the mortgage lender will mandate that, and in most cases even a church will be built via a construction loan and thus will have a mortgage. Usually the restoration makes the building as good or better than it was before. The contributions from other believers would probably be needed for upgrades that come naturally during a reconstruction, such as a new security system.
Our church has an unbelievable and frankly creepy security system. Sad to say, it has come in handy on a number of occasions. Putting it in was smart on the part of the pastor.
On the other hand, if for some reason the church in Wasilla did not have property insurance, they are idiots and will need help from the Body of Christ in basic reconstruction.
