Test me in this,” says the Lord Almighty, “and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it. I will prevent pests from devouring your crops, and the vines in your fields will not drop their fruit before it is ripe,” says the Lord Almighty. “Then all the nations will call you blessed, for yours will be a delightful land,” says the Lord Almighty.

2 Cor 9:8-14 (NLT)

And God will generously provide all you need. Then you will always have everything you need and plenty left over to share with others. As the Scriptures say,

“They share freely and give generously to the poor.

  Their good deeds will be remembered forever.”

For God is the one who provides seed for the farmer and then bread to eat. In the same way, he will provide and increase your resources and then produce a great harvest of generosity in you.

Yes, you will be enriched in every way so that you can always be generous. And when we take your gifts to those who need them, they will thank God. So two good things will result from this ministry of giving—the needs of the believers in Jerusalem will be met, and they will joyfully express their thanks to God.

As a result of your ministry, they will give glory to God. For your generosity to them and to all believers will prove that you are obedient to the Good News of Christ. And they will pray for you with deep affection because of the overflowing grace God has given to you.
