The Lord hates sacrifices brought by evil people,
particularly when they offer them for the wrong reasons. – Proverbs 21:27 NCV
God intended from the beginning for his people to be givers. That is, the kind of giver that does so honestly and willingly. Working around the spirit of godly giving is very disappointing to him.
One example is David. David refused to offer a sacrifice to God that he did not own. (2 Samuel 24:18ff) He understood that it’s not a sacrifice until we sacrifice something.
On the other side of the spectrum are Ananias and Sapphira. They tried to get credit for more than they gave. (Acts 5:1-11) They understood only the personal gain they would get out of the deal.
When God required the tithe from the Jews, and when he required the first day of the week offering for Christians, he was teaching us to be givers.
Giving changes us. It is about so much more than the money.
give, and it will be given to you. Good measure, pressed down, shaken together, running over, will be put into your lap. For with the measure you use it will be measured back to you. – Luke 6:38 ESV
