The use of your money and how you give it is one of the best ways of evaluating your relationship with Christ and your spiritual trustworthiness. If you love Christ with all your heart, your giving will reflect that If you love Christ and the work of His Kingdom more than anything else, your giving will show that. If you are truly submitted to the lordship of Christ, if you are willing to obey Him completely in every area of your life, your giving will reveal it. We will do many things before we will give someone else, even Christ, the rights over every dollar we have and ever will have. But if you have done that, it will be expressed in your giving. That’s why it’s said that your checkbook tells more about you than almost anything else.
