I'm sure this is something I will need to rethink (or repent of), but from a conversation an idea came up: creating a tithing brokerage firm. People could come and talk about their tithe portfolio. The client comes in and states:
I'd like to be 1/3 International missions, 1/4 in church planting, 1/4 inner city and please diversify the rest amongst…
The brokers would ensure these guidelines are met, investigate potential organizations, present these to the client and ensure the monies are being used appropriately. I imagine if you could build up enough clients you could start managing a pretty significant yearly giving amount. Of course, these funds should came after your support of the local church.
