Paul writes the Corinthians and essentially says; ‘I know you want to give, you boast about giving… so I am sending some people to collect for the Lord’ – So agents of the Church come and collect money from the Saints.
Now, Paul remind them that; “…He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.” (2 Corinthians 9:6) So we are taught that if we only give a little to the Church we are not going to be blessed as much as if we give a lot. So does that mean a rich person can get more blessings? NO! It means that you are giving a lot according to your means. For example: A poor person might give the church $10, but if that is 10% of their income (tithing=10%) then they have given according to the commandment, and will receive full blessings. What about the rich guy that gives $10 Million? If that is 10% of his income, then he also will receive full blessings.
Paul warns about those who give only for blessings, or give because they feel they are “forced”; “Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth the cheerful giver.” (2 Corinthians 9:7) When we give, we need to give with a cheerful heart!
