Anyone who can be trusted in little matters can also be trusted in important matters. But anyone who is dishonest in little matters will be dishonest in important matters.
I think you should finish what you started. If you give according to what you have, you will prove that you are as eager to give as you were to think about giving.
Each of you must make up your own mind about how much to give. But don't feel sorry that you must give and don't feel that you are forced to give. God loves people who love to give.
