2 Corinthians 8:1-7  And now, brothers and sisters, we want you to know about the grace that God has given the Macedonian churches. In the midst of a very severe trial, their overflowing joy and their extreme poverty welled up in rich generosity. For I testify that they gave as much as they were able, and even beyond their ability. Entirely on their own, they urgently pleaded with us for the privilege of sharing in this service to the Lord’s people. And they exceeded our expectations: They gave themselves first of all to the Lord, and then by the will of God also to us. So we urged Titus, just as he had earlier made a beginning, to bring also to completion this act of grace on your part. But since you excel in everything—in faith, in speech, in knowledge, in complete earnestness and in the love we have kindled in you—see that you also excel in this grace of giving.

Without God as our source of provision, we would have nothing.

Deuteronomy 8:6-18  Observe the commands of the LORD your God, walking in obedience to him and revering him. For the LORD your God is bringing you into a good land—a land with brooks, streams, and deep springs gushing out into the valleys and hills; a land with wheat and barley, vines and fig trees, pomegranates, olive oil and honey; a land where bread will not be scarce and you will lack nothing; a land where the rocks are iron and you can dig copper out of the hills.  When you have eaten and are satisfied, praise the LORD your God for the good land he has given you. Be careful that you do not forget the LORD your God, failing to observe his commands, his laws and his decrees that I am giving you this day. Otherwise, when you eat and are satisfied, when you build fine houses and settle down, and when your herds and flocks grow large and your silver and gold increase and all you have is multiplied, then your heart will become proud and you will forget the LORD your God, who brought you out of Egypt, out of the land of slavery. He led you through the vast and dreadful wilderness, that thirsty and waterless land, with its venomous snakes and scorpions. He brought you water out of hard rock. He gave you manna to eat in the wilderness, something your ancestors had never known, to humble and test you so that in the end it might go well with you. You may say to yourself, “My power and the strength of my hands have produced this wealth for me.” But remember the LORD your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today.

Giving of our money is seen as a grace, not as a work.

2 Corinthians 8:1-5 And now, brothers and sisters, we want you to know about the grace that God has given the Macedonian churches. In the midst of a very severe trial, their overflowing joy and their extreme poverty welled up in rich generosity. For I testify that they gave as much as they were able, and even beyond their ability. Entirely on their own, they urgently pleaded with us for the privilege of sharing in this service to the Lord’s people. And they exceeded our expectations: They gave themselves first of all to the Lord, and then by the will of God also to us.

Scripture promises that our generosity engages a cycle of God’s provision.

2 Corinthians 9:10-11 Now he who supplies seed to the sower and bread for food will also supply and increase your store of seed and will enlarge the harvest of your righteousness. You will be enriched in every way so that you can be generous on every occasion, and through us your generosity will result in thanksgiving to God.
