"Bring all the tithes into the storehouse, that there may be food in My house, and try Me now in this," says the Lord of hosts, "If I will not open for you the windows of heaven and pour out for you such blessing that there will not be room enough to receive it."
2 Corinthians 9:7-8 NKJV
So let each one give as he purposes in his heart, not grudgingly or of necessity; for God loves a cheerful giver. And God is able to make all grace abound toward you, that you, always having all sufficiency in all things, may have an abundance for every good work.
