Re: probably a silly question...building a house
That is a tough one, you might be better off stopping the tithe for awhile, until you get your feet set. You can still donate to the church, but a firm percentage, when going through tough financial issues is tough. There are two other things to give your church instead of Treasure if you are uncomfortable cutting back, Time and Talent.
Have you tried other sources of financing besides "banks" such as credit unions? You have "land" perhaps you should try Farm Credit Services.
Whenever you get mad over a called strike or ball on a close pitch, it's the equivalent of being mad at the QB pump-faking one time before throwing a pass in your average NFL game. ---Caveat Emperor
