You're welcome - I would say, "anytime" but I hope never to have to pray this way for you guys again! For other things, but not this.
Yeah, we used to have a catastrophic care plan and it was made obsolete right after we got married. Then we had an insurance plan which cost a whole lot and still had a deductible so high we'd be in debt a while if we ever had to use it. That's how we ended up with the CHM bill sharing program. It was cheaper than the Samaritan's Purse groups (I think there's three or four of those) because it was much older and had a larger pool of sharers. It's also grown dramatically since we joined.
My parents ended up with one of those stupid exchange things - we tried to talk them into bill sharing instead because it's much cheaper and would ultimately cover much more, but it's hard for them to imagine switching away from insurance...
And you're absolutely right: no matter how much we try to prepare, in the end it's always God who takes care of us and it's to him that we must surrender our attempts at planning.
