Among the "send it in" ministers who take the prize for pushing members to the brink and over at times is Dave Pack, Apostle and many other glorious titled founder of the Restored Church of God. Dave coined the "send it in" concept and is well known for his insane demands for retirements, homes, estates and any spare cash you may have just sitting doing nothing in the bank. If you wish to hear him directly commanding it, find a copy of "A Clarion Call" and be inspired or enraged depending on your orientation. (Exposés of "Clarion Call" can be found here and here.)
So to the point. Some simple concepts and rules the member should adopt in their giving, NO MATTER HOW THREATENING YOUR PASTOR GETS TO SEND IT IN.
I realize the Bible tells you differently in places and ministers can quote "God" to you all day guilting you out of your own mind and common sense if you allow it. Please remember, even if don't understand this. Human Priests in the OT wrote the OT and every rule in the OT that the masses must obey. If you do not understand this Bible fact, do your homework. It will easy your mind that you are not really offending a Deity that also says He owns the cattle on a thousand hills , which if He really needed money, He could sell since they belong to Him.
So here are the real rules if you wish to keep your own integrity in tack along with your mind and resources.
