God has a challenge for you.   

“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. “And I will rebuke the devourer for your sakes, So that he will not destroy the fruit of your ground, Nor shall the vine fail to bear fruit for you in the field,” Says the Lord of hosts; “And all nations will call you blessed, For you will be a delightful land,” Says the Lord of hosts.” Malachi 3:10-12

God challenges us to give to where we are being spiritually fed. Keeping back tithes from God can bring a curse.
