2 Cor 9:7 "...Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver..."
This sounds like more than a suggestion. It sounds like a requirement for Christians.
'..not reluctantly ...[not]under compulsion.' The problem for the Society may compound when the flock feels like they are 'under compulsion' and the desire wanes. Try to get someone to renew their desire when it disappears. It is almost impossible. Rev 2:4 made a statement that any adult can understand. Leaving or losing the love for something or someone you had at first, happens to all of us. When did you ever lose a first love and then rekindle it with the same fervor?
The Society tries to keep the 'love' strong by constantly changing the 'food on the plate'. New publications, new arrangements, new meetings, assemblies, exciting 'new light'. I wonder if giving because of hounding by the organization or guilt is more common than giving cheerfully.
I think there are enough examples in the Bible to prove God puts the motivation of the giver ahead of the amount. If the Governing Body has caused a decrease in cheerful giving, they should be preparing for a heavier judgement.
