2 Corinthians 9:7-8
Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver. And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
Everyone is to give as they have purposed in their hearts. We are not to give grudgingly or out of necessity, but cheerfully. As we give, needs will be met and God would be glorified.
